Description

one

The present invention relates to the field of information and control monitoring systems for measuring time intervals limited by two electrical pulses.

The device can be used in other technical fields related to the measurement of time intervals, for example, in radio physics, radio navigation, digital computing as information transducers, etc.

An analyzer is known in which the end result of a time interval measurement is represented as a sum of three time intervals. In this case, the integral part of the time interval is determined by a counting method and is recorded in the counter of the integer part. The other two intervals (the longitudinal parts comparable to the period of the quantizing pulse generator) are fixed on the delay lines.

The disadvantage of this device is that the increase in accuracy in the device is achieved through the use of high-speed scaling schemes and fast match schemes, as well as precision partitioned delay lines with a short delay time.

The aim of the invention is to improve the accuracy of measuring time intervals and expand the functionality of the analyzer.

In the proposed analyzer, this is achieved by constructing it according to a multichannel scheme, B of which, by introducing an entire unit selection block, the final measurement result is displayed in digital form.

The drawing shows the block diagram of the proposed analyzer.

Here: A and B are, respectively, the input terminals of the reference and interval pulses, limiting the measured time interval;

I is a generator of quantizing pulses; 2 - logical block; 3-b — Seven-block allocation schemes for targets of a portion of a time interval;

8- block allocation fractional part of the interval;

9- registration unit; 10 - delay unit;

II-block forming the time interval (on triggers).

The possibility of a static estimate of the time slots is associated with the need to determine the probability or frequency of coincidence of the partial, with respect to the neorode of the quantizing impulses Γ0, the cs1 of the time intervals studied with the numerical pulses. With single measurements of time intervals t, Tt, longitudinal segments occur both at the beginning and at the end of each dimension. In the proposed device, the final result of measuring the time interval is presented in the form:

the pulses of coincidence of the fractional, within up to Go, remnants of the beginning and end of the investigated time interval with quantizing pulses; N is the number of channels of the analyzer.

The generator 1 of quantizing pulses produces a continuous sequence of short pulses with a period of Go. The time interval, bounded by the reference and interval pulses, is applied to the input cells A and B. In the block of delay lines, the circuit of these pulses is shifted by time tsi (t-1) DG. Here, 2, 3 .... L,

and DG is the shift in the kth channel relative to N

(i-1) -th channel. From the output of the block 10 delay lines, the reference and interval pulses distributed over the channels enter the formation unit 11, in which the desired time interval ix is formed. These time intervals are shifted by a constant value Tz ;, are fed to the logical block 2, to other inputs which receives the pulses of the quantizing generator 1. In block 2, the measured interval is filled with quantizing pulses.

Due to the shift of the time interval through the analyzer channels, the first pulse of filling is not on all outputs of block 2, respectively, not all AND 3-6 circuits are opened.

According to the number of open schemes, "And in block 8, the fractional part allocation determines the ratio - and -. When at all outputs blol l
