A new ringing compensation technique by synthesis of waveforms is proposed. The technique is applicable for the sharp cut-off filters in modern TV receivers and new systems such as IDTV and EDTV which require increased horizontal resolution. The proposed compensation technique is subtracting the ringing compensation waveform from the filter output signal that contains ringing around the edges. This technique has excellent property of not to effect the frequency characteristics of filter. Moreover, the experimental results prove that the ringing between successive edges of signal, which had been difficult to be removed, is perfectly compensated.
