ABSTRACT OF THE DISCLOSURE In apparatus for recording, or otherwise transmitting, video or other information signals, and in which at least a portion of the signal to be recorded, for example, the luminance component of a color video signal, is frequency modulated and then passed through a filter for limiting the frequency band of the resulting frequency modulated component or signal which is recorded; a signal processor, such as, an automatic gain control or limiter, acts on the frequency modulated output of the filter to eliminate or compensate for amplitude variations that may occur therein by reason of the filter, for example, at portions of the signal where substantial pre-emphasis was applied. -1-
