A method and system for digitally scaling a waveform. A method is described performing a linear waveform transformation and translation of a curve in a smooth and continuous fashion. Another method is described for scaling a waveform in which the available accuracy and resolution is manipulated for a given waveform. Specifically, by strategically placing virtual tap points of a waveform, as well as changing the scaling factors used for calculating points on the waveform provides for adjusting the accuracy and resolution in one or more regions of a waveform. These scaling methods provide a digital equivalent of a voltage tap-based analog resistor ladder used for digital-to-analog conversion. The digital virtual tap points represent the analog voltage tap points, and the vertical translation of the curve acts in a smooth, monotonic, and continuous fashion.
