<p>FM-AM CONVERTER An FM-AM converter in which the FM signal is applied to a slope filter in a transmission system. The resulting amplitude modulated FM signal is applied to a circuit that derives a control signal corresponding to the mean value of the amplitude modulated FM signal and uses this control signal to control either the gain of the FM signal applied to the slope filter or the frequency response of the slope filter so that the amplitude of the amplitude modulated FM signal will have a predetermined mean value.</p> |
