Abstract
A gated peak detector capable of operating at frequencies of the order of 50 Mhz. and with pulse repetition rates of the order of 10,000 pulses per second includes high speed positive and negative peak detectors driving corresponding sample and hold circuits, the outputs of which are combined in a differential amplifier, the output of which is digitized to provide an output digital signal corresponding to the peak-to-peak value of the input waveform. An automatic polarity selector circuit sums the outputs from the sample and hold circuits, compares the sum to a reference voltage, and controls switches connected to the outputs of the sample and hold circuits and to the input of an analog sample and hold circuit which provides an analog output signal corresponding to the larger of the detected peak values.
