摘要： A waveform equivalent circuit for correcting the asymmetry of the rising and falling slopes of an isolated signal waveform retrieved from a magnetic recording medium so as to restore an acute, symmetric isolated waveform. In operation, the input signal is phase-shifted and attenuated, and then added to the input signal to produce a smaller double peaked waveform, which is modified with an inverted and attenuated version of the input waveform. The input signal waveform is subtracted from the modified double peaked signal waveform to diminish both slope sections, and an acute, symmetric original signal waveform is recreated.
