Abstract

PURPOSE: To improve the waveform deterioration of the output signal without imparing the noise elimination effect by limiting the signals of the high range component after clipping with other fixed level and then integrating the limited signals to add them equivalently to the signals the noise of which is eliminated.
CONSTITUTION: The video signals supplied to input terminal 11 are sent to low and high pass filters 12 and 13 each. And the output signal of filter 12 is sent to adder 15 directly, and the output of filter 13 is sent to adder 23 via bipolar clipper 14 and compensation circuit 20. The addition output sent from adder 23 is applied to adder 15 and then added with the output from filter 12 to be sent to output terminal 24. Circuit 20 possesses limiting diode 21 and integrating circuit 22 and gives the waveform operation to the clipped signals. Thus the component is obtained with its noise eliminated by clipper 14.
