Abstract
Disclosed is a method of generating electrical signal waveforms by a generator. The generator includes a digital processing circuit, a memory circuit in communication with the digital processing circuit, the memory circuit defining a lookup table, a digital synthesis circuit in communication with the digital processing circuit and the memory circuit, and a digital-to-analog converter (DAC) circuit. The method includes storing, by the digital processing circuit, phase points of a digital electrical signal waveform in the lookup table defined by the memory circuit, wherein the digital electrical signal waveform is represented by a predetermined number of phase points, wherein the predetermined number phase points define a predetermined wave shape. Receiving a clock signal by the digital synthesis circuit. Retrieving, by the digital processing circuit, a phase point from the lookup table. Converting, by the digital processing circuit, the retrieved phase point to an analog signal.
