Abstract

PURPOSE: To protect the error signal output at the instantaneous time of transmis sion line by locking an output signal when the output waveforms of a demodulator is always monitored and when two or more short pulses are continously generated.
CONSTITUTION: The phase comparison signal sent from a transmitter 21 passes through a receiving filter 23 from a transmission circuit 22 and is demodulated by a discriminator 24 and wave-shaped. Moreover, signals are output through an AND circuit 26. When a short hit is repeated, output is locked by detecting two or more consecutive short pulses through an output supervisory circuit 2. In addition, a hit detection circuit 27 need not detect the short hit and the signal transmission circuit is simplified.
