Abstract

PURPOSE:To avoid the divergence of the automatic equalizer in the MODEM of the data communication by inhibiting the control of the tap gain for the equalizer while the output voltage fluctuation of AGC is being detected. CONSTITUTION:When the level hit like sector II of reception input A occurs, rectification waveform D of AGC control voltage C and AGC output varies and the signal emerges to output E of comparator circuit 8. And the operation of tap gain control circuit 7 is inhibited while the signal exists. As a result, the tap gain of automatic equalizer 4 is held atthe value before occurrence of the level hit of the circuit, avoiding the divergence of equalizer 4.
