Abstract
An impulse noise detector for detecting impulse noise in video signal includes a band pass filter for passing a band of video signal frequencies centered in the spectral region of video signals which exhibit a relative energy minimum. The band pass filtered signal is applied to a vertical comb filter. A threshold detector is coupled to the output connection of the comb filter for detecting the occurrences of impulse noise.
