NOISE CHARACTERISTICS 43frequency modulation improvement is doubled for carrier-noise ratiosabove the improvement threshold; second, when the improvementthreshold occurs in the frequency modulation receiver, the carriernoiseratio existing in the amplitude modulation receiver is one halfof what it would have been without the transmitter power gain.AcknowledgmentThe author thanks Mr. H. H. Beverage and Mr. H. O. Petersonfor the careful guidance and helpful suggestions received from themduring the course of this work. The assistance of Mr. R. E. Schock inthe experimental work is also appreciated.
