Abstract :
The letter presents a different view to that customarily adopted, and calculates the expected number of clicks per second at the output of an f.m. detector. It is shown how the above-threshold expression for the instantaneous frequency can be used in a very general result, from which the click-rate formulas given earlier by Rice for modulated carriers can be simply obtained.
