The inputs 28 and 29 of the imaging unit 1 are respectively supplied with a sequence of time intervals, specified either as a period T, or a duration t of pulses, and a signal for selecting the type of time interval; input 30 of the gating unit 13 is the signal of the research interval (gating), at the end of which the measurements of the limiting values of the time intervals at the outputs 31 and 32 of registers 7 and 8 of the limit values are recorded and, respectively, the maximum and minimum values of the time intervals are recorded. in the mode of measuring the function or density of the distribution in time intervals, the counters 26 and 27 are recorded, respectively, the number of time intervals located in a given Range and the total number of time intervals; 33 elements to the input

And the census .5 and - signal, measurement of limit values, to the input of 34 elements And records 22,23,24,25 signal Measurement function or

At inputs 35 and 36 of the elements And records 22 and 23, the codes of the maximum and minimum values of the set range of values of time intervals, respectively.

The analyzer works as follows.

1. Measurement mode of limit values of time intervals.

The choice of this mode of operation ody is implemented by applying a signal to the input 33 and a signal b to the input 34.

In the absence of a gating signal. At input 30, key 2 is blocked by signal O received from the first output of gating unit 13, and registers 7 and 8 store the result codes of the previous measurement. Shaper 1 generates, at its second output on the leading edge of the signals arriving at its input 28, pulses of a fixed duration ..

Let the sequence of time intervals be specified as a pulse period, TX at input 28, and a single signal at input 29. The last to the first output of the imaging unit 1 and unlocking the key 2 via the first control input. When a single signal is applied to the input 30, which sets the strobe interval, block 13 generates a signal at its first output that unlocks the key 2 according to the first pulse from the second output of the imaging unit 1 control input. As a result, the pulses of the generator 3 through the key 2 begin to arrive at the counting input of the counter 4 and to one of the inputs of the synchronization unit

14. The last one is triggered by going to its other input of each impulse from the second output of the imager.

1. At the same time, on the falling edge of the first block 14, the pulse 3 of the generator 3 is formed at the first output of block 14, a pulse arrives at the signal inputs of keys 18 and 19 and allows census (code) and record elements 24 and 25. The next pulse of generator 3 passes directly to the second you: the stroke of the block 14 and sets the counter 16 to the zero state and the counter 4 to the unit state. At the end of this pulse the block 14 returns to its initial state, and the counter 4 starts counting the pulses arriving to his counting input. In the counting process, the counter code is 4

. is continuously compared using comparison circuit 12 with register code 7 or 8, arriving at its inputs, respectively, through AND 9. or 10 and the element IDI11. At the moment, the equality of the codes of the counter 4 and one of the registers, the comparison circuit 12 generates at its output a signal that arrives at the counting input of the counter 16 through the prohibition element

15, divided by D7Okirovanny in the pause between pulses from the output of the key 2. To mo-.

The time of the next operation of the synchronization unit 14 in the counter 4 will be fixed to the current value of the time interval being studied. The latter is rewritten to register 7 or 8, respectively, through the element AND 5 and the element OR 20 or the element AND b and the element OR 21 according to the signals from the upturns of the corresponding keys 18 and 19 at the moment of the appearance of the signal at the first output of the block 14.

0 Then, the counter 4 is reset, as described above, and continues to count the pulses arriving at its counting input.

five

The state of the Keys 18 and 19 and the And 9 and 1Q elements is determined by the state of the counter 16, counting the number of signals from the output of the comparison circuit 12. The elements .. And 9 and 100 are controlled directly, and the keys 18 and 19 through the switch 17 signals from the direct and inverse outputs of the first and second bits of counter 16, so that in the initial zero state of the last unlocked

5, an element of AND 10 and a key 19. As a result, at the beginning of the next .. time interval T j, the code of the number dialed in the counter 4 is always compared with the register number code 8.

D

If the current 1st time interval TX is less than the time interval Trinin whose code is recorded in register 8, then the comparison circuit 12 does not work, the counter 16 remains in the initial zero state and during the next operation of the block.14 the pulse from the first output of the last enters through key 19 on input control element b and unlocks it. As a result

0B register 8 rewrites counter code 4, corresponding to a newer shorter time interval,

If f .Tftiin ° the moment of the next operation of the block 14

5, the code dialed by counter 4 is compared to the code recorded in register 8, and at the time of the equality of the codes at the output of the comparison circuit 12, and consequently, the output of the prohibition element 15 is a signal that sets the counter 16 to the first state In this case, the element 10 and the switch 17 are blocked, and the element 9 and unblocked and the input code of comparison 12 receives the register code 7 corresponding to the time interval T max If at this time T T o repeated operation comparison circuit 12 does not happen and by the time

On the next operation of block 14, the counter 16 remains in the coJCTO of the corresponding unit of the account. Since in this case, the switch signals 17 is locked, the keys

Claims (2)

5 18 and 19 are blocked and 9 registers 7 and 8 remain codes corresponding to the same values of T, groin T, r ". If it turns out that T 7 T, then the comparison circuit 12 will work a second time and set counter 16 to the second state, corresponding to two units of account. Switch 17 is unlocked again and the signal from the corresponding output of counter 16 unlocks the keys 18. When the block 14 is triggered again, the pulse from the first output of the last goes through key 18 to the control input of the element 5 and unlocks it. As a result, counter 4 is written to register 7 corresponding to a new larger time interval,. When the signal from input 30, defining the gating interval, arising on the first pulse from the second output of shaper 1, signal O from the first output of gating unit 13 blocks key 2 and the measurement process ends. Thus, the analyzer provides, at T, a copy of a new smaller time interval in register 8, and at T, an overwrite, a new large time interval in register 7, and, therefore, at the end of the gating interval in registers 7 and 8, the maximum and minimum values of the time interval will be fixed, respectively, in the gating interval. From one of the control inputs switch. The coil 17 with the second output of the block 13 provides for writing to the registers 7 and 8 of the code corresponding to the value of the first time interval T on the strobing interval regardless of the state of the counter 16; Keys 18 and 19 are unlocked by screen scrap generated at the second output of block 13 when a signal is applied to input 30, and fed through switches 17 to the inputs of the control of these keys, while at the first place the bits of elements 9 and 10 are respectively signals and O /, which ensures the correct functioning of the analyzer with the validity of the codes recorded in registers 7 and 8, if the subsequent time interval is greater than the previous one. The signal is removed from the second output of block 13 after the second pulse arrives at its second input from the key 18, and further control of the keys 18 and 19 is determined by the state of the counter 16, as described above. When a sequence of time intervals is specified at input 28, a sequence of pulses is applied to input 29 of generator 1 and a signal O is sent at its first output, a single signal is formed that unlocks key 2 for a time equal to the duration of the input pulse. In the rest, the analyzer does not differ from that described above. , And, the mode of measuring the function or density of the distribution of time intervals, the choice of this mode of operation of the analyzer is carried out by applying a signal to the input 34 and a signal O to the input 33, and the elements AND the censuses 5 and 6 are blocked by one of the control inputs, and the elements AND records 22 and 23 are unlocked by the control input and through the elements OR 20 and 21, the codes defining the limits of the studied range are recorded in registers 7 and 8 of the limit value codes, ONE. A HULL signal at the input 34 unblocks the elements AND records 24 and 25 through one of the control inputs. The operation of the analyzer in this mode differs from that described above ... in that copying codes from counter 4 of the current values into the registers of codes -7 and 8 is prohibited, and boundary registers are stored in these registers The x values of the range, which are incremental on., inputs 35 and 36, while measuring the distribution function, input the minimum time interval code, and input 35, the code corresponding to the analysis level, when measuring the distribution density, input 3 the code corresponding to the lower boundary of the differential window, and the input 35 - the code corresponding to the upper boundary of the differential window. The current time interval values are compared with the limit value codes in registers 7 and 8, with the counter 16 (code equality signals) being set to the appropriate state. In the states of counter 16, corresponding to the unit of account (TU), And record 24 is unlocked by the control inputs and signal from the first output of the block. 14, a unit is recorded in counter 26. The counting input of the counter 27 through the entry And the record 25 receives all the signals from the first output of the block 14. Thus, the code in the counter 26. will correspond to the number of time intervals whose duration is in a given range (TmiM T), the code in the counter 27 - the number time intervals received at the input of the analyzer, and the ratio of these values will be an estimate of the function or density, distribution of a random variable. The introduction of new features — the elements AND records, the OR elements, and the counters — expands the functionality of the analyzer, making it possible to measure the function or density of the distribution of time intervals.
