White clipper
![The line waveform with excessive white level at the input and at the output of the clipper. In this example, a standard sawtooth wave is used. Note that the signal is clipped but not attenuated.](/Images/godic/202502/20/White_clipping5604.jpg")
A white clipper (or white limiter) is a circuit in professional video products that limits the maximum amplitude of the luminance part of the analogue video signal to 1 volt. It is essential for both analogue recording and transmission of video material.
