Abstract:

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. Digital filtering and detection techniques have enhanced signal processing with the aid of faster hardware and efficient software to provide a logic signal indicative of a desired energy within the pass band and to preserve the signal amplitude. A microprocessor controlled digital detector has a center frequency and bandpass which can be changed as a function of time. Amplitude signal information can be preserved. Input signals are shaped for digital processing. A peripheral interface adapter formats these inputs for the microprocessor which is under both ROM and RAM program control for determining the center frequency. The microprocessor output is through a peripheral interface adapter.
