ABSTRACT:
Structure for and a method of detecting peaks in an electric signal comprising circuits for and the steps of converting a selected one of a plurality of analog signals into a current digital signal, comparing the developed digital signal with a digital signal previously developed from the selected analog signal and stored, and replacing the previously developed and stored digital signal with the current digital signal when the current digital signal is greater than the previously developed and stored digital signal and of the same polarity, and providing for readout of the currently stored digital signal in either analog or digital form.
Direct reading of the digital output in terms of standard engineering units is provided for. Also, the analog input signal may be directly read at the output of the peak detector and the peak detector may be utilized as a volt meter with a direct current signal passed directly into a digital output portion of the peak detector. The peak detector may be operated automatically or manually and upper and lower peak signals may be reset manually.
