Abstract
PURPOSE: To enable to perform data reproduction with high accuracy by following the level variance, by operating the gate circuit based on the detected output of the synchronizing separation circuit to detect the maximum and minimum values of the signal and enabling level decision of reproducing signal based on this.
CONSTITUTION: The reproducing signal from the tape recorder recording the digital data signal with false television signal is input to the synchronizing separation circuit 13, and the gate switching control at the gate circuit 12 is made with the detected output, and only PCM signal is fed to the maximum voltage detection circuit 15 and the minimum voltage detection circuit 16 as the data signal to respectively detect the peak values of input signal. The level difference at the detectors 15, 16 is output to the comparator 11 as the comparison reference signal and the data identification is made for the reproducing signal from the video tape recorder for data reproduction.
