Abstract :
A method is described wherein crystal-controlled phase- or frequency-modulated carriers may be produced having relatively large deviation angles. A circuit is described wherein the harmonic distortion during modulation is held to a low value. An experimental transmitter is shown utilizing one form of the system. Also shown are oscillograms of the voltages occurring in various portions of the modulation system.
