Abstract
A digital audio waveform display is presented on a digital video waveform display instrument using the video waveform display circuitry. A decoder extracts embedded digital audio data from a digital video signal. The digital audio data is stored in a buffer memory. N digital audio data words, corresponding to N samples of the video data representing a video line for display, are read from the buffer memory at a video sample rate and input to the video waveform display circuitry. The video waveform display circuitry includes a digital to analog converter operating at the video sample rate and an analog video reconstruction filter which provides amplitude values for a swept display device.
