This book was released on 1960 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research concerns the suppression of the randomnoise threshold effect in FM systems by applying strong regenerative feedback around the amplitude limiter. Little or no threshold suppression is predicted. This conclusion is reached analytically by retaining a nonzero correlation coefficient between the IF and the feedback noise throughout and by introducing a functional expression to take into account the effect of regenerative feedback on results derived by Davenport. A simple conceptual argument is also presented in support of the analytical findings, and some practical aspects of regenerative limiter implementation are considered. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Investigations into the FM threshold phenomenon have resulted in the development of several signal processing techniques that can be implemented at the output of any FM demodulator, including phase lock loop and FM feedback demodulators, to provide improved system performance. These techniques are based on the distinguishing characteristics of the demodulator output noise below threshold. Performance improvement and threshold extension are achieved by operating on the demodulator output signal and noise such that the threshold noise impulses are eliminated. The characteristics of three postdetection threshold extension techniques are evaluated with respect to the ability of such techniques to improve the performance of a phase lock loop demodulator. These techniques include impulse-noise elimination, signal correlation for the detection of impulse noise, and delta modulation signal processing. Experimental results from signal-to-noise ratio data and bit error rate data indicate that a 2- to 3-decibel threshold extension is readily achievable by using the various techniques. This threshold improvement is in addition to the threshold extension that is usually achieved through the use of a phase lock loop demodulator.
