STAND FOR STUDY WORK RECEIVER TONE track circuits

摘要

The invention relates to the means of study and can be used in the educational process to study the work of receivers tonal track circuits. The technical result is to increase the reliability of information on the faulty receiver elements. The technical result is achieved in that a stand for studying the receiver tonal track circuits comprising a source of the desired signal, which includes a manipulator, a source of interference, the adder, the receiver tonal track circuit comprising a first threshold device, and the second threshold device, an input unit malfunctions, indicator switch and a memory unit, wherein the useful signal source and the noise source via the first and second combiner inputs respectively connected to the first input receiver tonal track circuits, the second Rin od coupled to an output fault injection unit, 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 the first input of the indicator, the second input of which is connected to the output of the storage unit, the input of which is connected to the output of input unit fault additionally introduced error calculating unit, wherein the first and second inputs of the error calculation unit connected to the outputs of the manipulator member and the first threshold, respectively, and output to the third input indicator.
