Comparison of AM and Narrow - Band FM UHF Communication Systems. Appendix C: Design and Performance Characteristics of Equipment Employed

Abstract

A description is provided of the principal design and performance characteristics and the receivers, transmitters, and recording equipment used in the comparison of am with narrow-band fm in the uhf range. Comparison of a-m with f-m characteristics is made wherever possible. Such measurements as selectivity, resonant overload, signal-to-noise ratios, sensitivity, discriminatory response, capture effect, overall frequency response, and modulation characteristics are describe. In addition, deficiencies observed during the course of the a-m and f-m systems' evaluation are outlined.
