Abstract :
In telemetry system the technique of voltage comparison has traditionally been used in the monitor receiver to search and to lock a continuous signal or a pulse one, which width is over several millisecond. However, when a signal tested Is a very narrow pulse, it is impossible to use the technique of voltage comparison to catch these signals. The paper introduces a method of counting pulse to search and to lock very narrow pulses (their width>50 ns), which presents a new and a feasible technology for the reception of narrow pulse system
