FREQUENCY MODULATION NOISE.
Abstract
The noise characteristics of a commercial FM receiver were determined experimentally and compared with the theoretical results of Middleton and Stumpers. The theoretical solutions are derived on the basis of both gaussian and rectangular receiver IF characteristics. The experimental results follow the rectangular solution for low carrier to noise ratio and the gaussian solution for high carrier to noise ratio. This is explained by the characteristics of the receiver and FM noise theory. A novel technique, employing an envelope detector, is used to measure carrier to noise ratio prior to the FM detector. The thesis also includes information helpful in consolidating the FM noise theory in the literature.
