Abstract
PURPOSE: To prevent the malfunction caused by the noise by drawing out the synchronous pulse via the serial capacitor and then adding the DC voltage to the synchronous pulse to then supply it to the logic product circuit.
CONSTITUTION: Synchronous pulse A delivered from synchronous isolation circuit 2 is converted through capacitor 12 into the waveform whose average level features OV and with its peak reduced. Furthermore, the amplitude is reduced via resistance 13, and the DC voltage divided through resistance 14 and 15 is applied to the signal from +B voltage. Then the waveform shaping is given to the signal so that the peak value may exceed the threshold voltage of AND circuit 3, and such signal is supplied to circuit 3. As a result, reception detecting signal C is generated. While in the state under which the channel is not received, the noise caused at circuit 2 is lowered less than the threshold voltage of circuit 3 to be supplied to circuit 3, and no output is generated from circuit 3. Accordingly, the decision to the reception state can be prevented completely.
