Digital detector |
摘要 |
A digital detector which responds to sinusoidal or square wave input signals to detect the presence of a particular frequency or band of frequencies and provide a selectable digital output indicating the presence of this frequency or band. A gated pulse generator operates in response to the input signals, providing pulses that are counted by a binary counter and sensed by a decoder which detects the presence or absence of the frequencies within the selectable bandwidth limits.
