Signal monitor and interference suppressor - uses pulses from two monitoring channels which connect receiver demodulated voltage to filters followed by stores

摘要

The device is used during point-like signal transmission between a mobile station with a transmitter or a receiver, and a fixed station with a receiver or a transmitter. The output pulse of a monitoring channel (14, 17), for the amplitude of the receiver input voltage, and the output pulse of a monitoring channel (15, 16, 19, 20, 22) for the amplitude of the input voltage of the receiver with a pickup delay timer (20), together operate a switch (4) which connects the receiver demodulated input voltage to a filter (51-55) whose output signals are stored. The stores (71-75) are controlled by the output pulse of the channel containing the above timer (20).
