Description

the source of the sample numbers and with the counter input; the second pulse generator output is connected to the counter subtraction input and through the third delay element to the second inputs of the second and third keys, the output of the second key is connected to the third control input of the register, the output of which is the output of the device, and the output of the second element ed: The cable is connected to the second control input of the adder. The drawing shows the proposed calculator, a block diagram. The calculator contains a source of 1 sample numbers, adder 2, register 3, generator 4 pulses, counter (pulses) 5, first and second blocks of elements And 6 and 7, first, second and third delay elements 8, 9, 10, first , second and third keys 11, 12, 13. The calculator works as follows. -: .... SOURCE 1 sampling numbers after each pulse fed to its input, connected to the first output of the generator. 4 impulses, forming At its discharge potential outputs. X; samples in binary code; after the formation of Xj, an impulse arises on it. a control output connected to the first input of the pulse generator. This impulse is nocTynaei to the master of the matrix, and the adder adds to its content the number that is present on the output of the source. Adder 2 calculates the sum: ,, 27x. -n-o-fп п-} 1 where Q is the true value of the measured quantity ;: D - random measurement error; .ni; - -n - the number of measurements. In the initial state, the adder 2, the register 3 and the counter 5 are set to zero, the pulses at the outputs of the generator 4 pulses are absent. The number 2Go is the block parameter And 6 is set so that the following inequality is satisfied:), (2): where and (() is the minimum number sufficient to obtain the required relative accuracy (for L-O; if dbs is tagged n 1 already at some of the ocwj a2 th only the weaker constraint should be satisfied: C, (b -). (3) The single signal at the first output of the AND 7 block is present when the number 5 vaa 2 is fixed on the counter 5. only in one bit. A single signal at the second output of the AND block 7 is present only in the zero state of the sc 5. Block AND 7 participates in dividing the sum by P. After starting the pulse generator, it generates a pulse at the first output, thereby starting the source of the sample numbers and writing the unit to the counter 5. Generating Xj .. The first 1 sample of the sample is, source 1 generates a pulse at the control output.This pulse causes the adder 2 to add the number X to its content, goes to the first input of the pulse generator, and through the delay element 8 goes to the control input of the AND 6 block, Since at k-0, the output of the AND block 7 present high / potend I balked, i.e. key 11 is open. If ii Xf fe-So, then the pulse coming from the output of the delay element 8 causes the appearance of a pulse at the output of block 7. 7. The output pulse, pass through key 11, goes to the first control input of register 3, putting into it the contents of adder 2 i.e. the number xi, as well as to the third input of the pulse generator, which, without forming the second pulse at the first output, goes into the division mode and starts generating pulses at the second output. The first of these pulses, arriving at the subtracting input of counter 5, returns it to zero, whereby a single potential is established at the second output of AND 7, the key 13 opens, and the pulse delayed by element 10 passes to the second input of the generator, pulses 4, returning it to its original state earlier than it will have time to form a second pulse at the second output. The impulse arriving at the first input of the register 3, through the delay element 9, will also arrive at the second control input of the adder 2, returning it to the initial state. Thus, in register 3 it turns out to be the value of x, as the arithmetic average of the sample of the volume p. Consider the operation of the circuit in the case of X Z about. In this case, the pulse at the output of the block And 6 will not occur, and the generator 4

pulses, not having received a pulse on the sample nickname of the sampling numbers, checker, regisgr, switch, will continue to work and will generate a pulse generator in the first place, a pulse at the first output. The development of this and the fact that, with the aim of raising the number and summing them up, will continue to be inaccurate, two blocks are entered into it until s elements AND, three delay elements are met and two conditions are met: inequality (2 ) or an adder, with informational inputs

(3) and equalities of the curl are connected to the correspondence 2, c, 2. , After the first condition is satisfied, the summing pulse from the output of the bumagor delay element 8, with the first generator input, will cause a pulse at the output of the pulses and, through the first element Delay 6, however, the And key will be closed until those with the control of the entrance to the first block of the pores, until the well is completed, and the information inputs are closed (4). As soon as this happens, they are merged with the information in the impulse from the output of AND 6 block will pass through. Dame and register and are connected to the appropriate key; 11 And will transfer the contents of summagus — vuschuyu1sm Bzh) I will give summagor, the output of the first 2 in the register 3, will reset the adder of the Vgo block of elements And is connected to the first

zero and translates the pulse generator 4 input of the first to / Aoch, the second input of the KOG division mode, i.e. will begin to generate pogo combined with the input of the second with pulses at the second output. Let it be the key and connected to the first output of the second occurred at k-1, i.e. / t 2, the ry block of elements And, in which the

When the Ozaderzh-delayed element is connected to its output terminals and the first impulse from the second Getschik output, the second output of the second block of the 4th generator will go to keys 12, and 13, And elements connected to the first input

the key 12 will be open, and the key 13 is the third key, the output of which is connected is fixed, since on the counter 5 it will be with the second input T of the pulse generator, the number 1 2 is fixed. The third input of which is combined with the first pulse will pass through the key 12 and shift. the control input of the register, with the input of the contents of the register 3 for one bit in the second delay element in subalue. the side of the younger Raids, i.e. {Extending to the output of the first key, the output of the ge is the number on the willow, thereby calculating the energy of the pulses / connected by an input

The second counter output of the generator of the generator 4 will go to the keys 12 and 13, and the pulses are connected to the input of the subtraction when counter 5 returns to zero, i.e. the counter and through the third element only hooks 13 will be delayed, in peaynt ki to the second inputs / second and third generators 4 will be installed in the Wrench, the output in the firing key is connected to the walkable state. the control input of the register, if it turns out that the output of the device is output by the device, is similar.
