RANDOM ERROR OF PULSE DURATION MEASUREMENT WITH OSCILLATIONS AT THE TOP BY MULTI-THRESHOLD DURATION METERS

Abstract

In systems for automatic measurement of the duration of video pulses, various devices for amplifying and shaping pulses of a normalized level are used, the duration of which is equal to the duration of the input signals. A rough measurement of the duration of video pulses can be made with onethreshold meters. More accurate are multi-threshold and floating-threshold meters. Pulse duration meters have found wide application in electronic warfare equipment, in measuring technology. The variation in the shape of electrical signals does not allow the use of a single measurement method, which is the best for all shapes, therefore, the search for technical solutions that satisfy the conflicting requirements continues: a wide range of durations and duty cycles. The aim of this work is to carry out a mathematical analysis of the random error in measuring the pulse duration with oscillations at the top by multi-threshold duration meters. In the course of the work, the results of a numerical experiment were obtained to measure the duration of a pulse with oscillations at the top using multi-threshold duration meters. And also a comparison was made of four multi-threshold duration meters for the investigated pulse shape. The calculation results are presented for a signal dynamic range of 60 dB and an amplitude quantization step of 3dB and 12 dB.
