Abstract
Peak capture circuitry for measuring a peak value of a waveform characterized by a first portion having a first rate of change and a second portion having a relatively faster rate of change. Peak stretching circuitry stretches a portion of the waveform as a function of time. Digital signal processing circuitry samples an output waveform of the peak stretching circuitry for determining the peak value. Thus, despite any steeply sloped portion, samples can be reliably taken throughout the waveform for calculation of peak value.
