Abstract
A simultaneous signal detector includes components for scaling, by the total signal strength, the difference signal resulting when signals having different frequencies are simultaneously received. As a result, only those inputs which meet both frequency and amplitude difference criteria result in an active SS indication, thereby reducing the number of false active and inactive indications.
