Performance of receivers and signal analyzers using broadband frequency-sensitive devices

The report compares the performance characteristics of a class of receivers intended for spectrum monitoring or signal analysis. A broadband frequency-sensitive element provides the basis of operation of the receivers considered--sometimes called frequency-discriminator receivers. Five different receivers are defined according to the method used to separate amplitude and frequency information. Two of the receivers produce a voltage analog of instantaneous frequency, two produce cathode-ray-tube displays of instantaneous frequency vs instantaneous amplitude, and one produces a binary digital indication of instantaneous frequency. These systems are compared with one another and with an array-of-filters spectrum analyzer. The bases of comparison include dynamic range, power sensitivity, frequency sensitivity, accuracy of measurement, ambiguity, response time, resolution of simultaneous signals, responses to special signals, and complexity.
