Abstract

PURPOSE:To prevent pictures from deteriorating in quality by suppressing waveform distortion by limiting the amplitude of an input to a digital low-pass cutting-off filter that eliminates a DC offset. CONSTITUTION:The output voltage of bias circuit 1 is roughly adjusted to the center part of the dynamic range of A/D converter 3 when input signal X(t) is 0V. Input signal X(t) it converted into a digital signal by A/D converter 3 and then parallel-series converter 4 cnverts it into series data and also limits its amplitude. The amplitudeliminated digital signal has its DC offset removed by digital low-pass cutting-off filter 6 and is applied to digital arithmetic part 5.
