ABSTRACT:
Apparatus is provided for automatically peaking a luminance signal in response to the signal-to-noise ratio of a received signal. Manual adjustment means are also provided whereby the luminance signal may be "peaked" to increase the slope of transitions in the luminance signal, or "depeaked" whereby the slope of transitions of the luminance signal is decreased.
