Second Report on Panoramic Receiver CW Thresholds

Abstract

The problem of perception by an observer of signals in the presence of receiver noise, as presented on the cathode-ray tube indicator of a panoramic system, is further considered. Additional data are given on the effect of variation of video bandwidth on minimum perceptible signal. A tentative form of an expression for minimum perceptible signal is derived as a function of the system's parameters, and it is found that, with respect to sweep rate, a minimum occurs in the expression at about 14 c/s. The range limits of the various parameters, presented graphically, may be useful as a guide in design procedures.
