Abstract
PURPOSE:To hold a signal level and to obtain a video display signal which makes the luminance change clear at video display, by subjecting waveform processing to a signal indicating a large change without changing the signal level. CONSTITUTION:An input signal indicated in solid lines A passes through a low pass filter 1 and is changed to a signal shown in dotted line of A. The output signal of this filter 1 is compared for the signal level with the said input signal at a comparator 2, and the output signal of the analog switch 3 as shown in B is obtained by controlling the analog switch 3 with this output signal. Thus, the waveform signal consisting of larger signal level than the passed input signal level through the low pass filter 1 is outputted.
