ABSTRACT:
In the digital detector the center frequency and bandwidth of a digital fer is controlled by a microprocessor. Amplitude information for the original input signal may be preserved or a simple threshold of energy may be detected within a bandpass. The microprocessor scans a selected frequency spectrum by digitally changing the decoding data controlled by software. This detector in conjunction with a scanning algorithm permits data acquisition in addition to energy detection, data acquisition being the process of controlling an incoming signal within a bandpass by moving the center frequency and bandpass of the filter and generating a corresponding error signal as the feedback control signal.
