Abstract

PURPOSE: To compensate interference between codes by simple constitution by controlling the gain of an equalizing amplifier at either or both a half or/and a quater of a pulse repetitive frequency.
CONSTITUTION: Detector 10 is provided which detects inter-code interference pulse period T0 or 2T0 twice as long as it after the period in time when the output waveform of equalizing amplifier 9 equalizing and amplifying an input signal shows its peak value. Then, the output of this detector 10 has its gain increased or decreased at either or both a half or/and a quater of the pulse repetitive frequency of equalizing amplifier 9. Further, the gain of equalizing amplifier 9 during period T0 or 2T0 from the peak value of the output waveform is increased or decreased by the simple constitution to compensate interference between codes.
