Abstract
This dissertation describes and synthesizes a new member of the family of FM detectors introduced earlier by Klapper and Kratt. A salient property of these detectors is low delay with excellent sensitivity. The emphasis in the new detector is on the ease of digital implementation. In addition, the new detector is also extremely linear. In congruence with the other Klapper-Kratt detectors, it makes use of zero group delay elements, balance at RF, quasi-synchronous detection and carrier cancellation. The Performance of the detector is mathematically analyzed under the conditions of a modulated input wave, sinewave [sic] interference, and noise. The results indicate improved Performance over other members of the family in terms of linearity, threshold, and ease of digital implementation. Realization of the detector using FIR digital signal processing methods is discussed, including linearity optimization. Substantial algorithm simplification was achieved. High center frequencies with low sampling frequencies are obtainable due to the frequency foldover effect. Narrowband predetection filtering can be included in the detector provided a wider predetection filter is Present. Results of a working model are shown.
