A technique utilizing either particular software with a microprocessor or computer or a hard wired digital or analog circuit for determining, from a few sample magnitudes acquired from an analog signal at equal time intervals, the shape of the waveform and displaying it. The analog waveform slope at each sample is calculated from the magnitude of the two samples taken from the waveform immediately preceding a given sample and the two immediately following the given sample. A slope of the analog waveform intermediate of each sample interval is then calculated from this information, leading to a final calculation of the magnitude of a selected number of points during the sample interval. The acquired sample magnitudes and the calculated intermediate magnitudes are then combined in a display of a reconstruction of the original analog waveform.
