ABSTRACT:
A pulse signal is received at the input of a wide band receiver. The signal is then processed through a plurality of narrow band channels. Each of the narrow band channels are compared to adjacent channels to produce a series of "ESS" curves whose amplitude is responsive to frequency of the incoming signal. The absolute magnitude of these "ESS" curves are compared one to the other to determine the greater of the relative energys in each of the narrow band channels and logic signals are produced therefrom indicative of the incoming signal frequency.
