Abstract
A digital waveform generator is used to generate n periodic waveforms which have the same shape. It has a memory store into which is store a series of preset numerical values representing samples of a wave, and a unit to control the output of the memory store and to generate the wave. The unit is driven by a clock. The unit has a counting assembly followed by an encoder. The counting assembly has a binary counter controlled by the clock. A computing unit is connected to the counter and to an auxiliary memory in which is stored an initial periodic ratio. The clock provides the sampling frequency and the counting assembly provides the periodic ratios at definite instants to give the waveform required.
