Abstract: A circuit for blanking unwanted error-causing peaks in the waveform derived from the reading of high density magnetic recordings wherein the data waveform is filtered by a low pass filter and variable Q resonant filter to generate a rectangular wave blanking signal applied to a flip-flop together with the equalized signal, whereby false peaks in the equalized signal are prevented from triggering the flip-flop by the blanking signal.
