Abstract
A system for producing a signal representing an envelope waveform corresponding to the minimum and maximum excursions of an underlying signal includes a source of the underlying signal and a signal acquisition circuit coupled to the underlying signal source. A circuit for calculating the envelope of the underlying signal is coupled to the signal acquisition circuit to produce an envelope signal. A rasterizer, coupled to the signal acquisition circuit and to the envelope calculating circuit, generates the envelope waveform representative signal being a single raster displaying waveforms representing the envelope signal and the underlying signal.
