STAND FOR STUDY WORK RECEIVER TONE track circuits

摘要

The utility model is aimed to expand the functional capabilities, to increase reliability of information in the study of the principles of construction and operation of track circuits tone receivers due to the comparative analysis of the signal response parameters at the output of each receiver element at their proper and defective condition. Knowledge of deviations, signal feedback parameters allows detection of a fault in a particular cell, that occurs as a result of damage to the actual operating conditions. The technical result is achieved in that a stand for studying the receiver tonal track circuits comprising a source of the desired signal, the interference source, the adder, the receiver tonal track circuit, the second threshold device, an input unit malfunctions, a switch, indicator, wherein the desired signal source and a noise source through first and second combiner inputs respectively connected to the first input receiver tonal track circuit, a second input coupled to an output of input unit malfunctions, and the first and second outputs respectively connected to the input of the second threshold device and to the input switch, whose output is connected to a first input of a two-channel indicator, is additionally introduced memory unit, and the indicator is formed two-channel, wherein the storage unit input coupled to the output of input fault block, and output to a second input of the two-channel indicator. 1 Fig.
