Abstract
A process and an apparatus using an inverse discrete Fourier transform for ynthesis of complex waveforms that have one or more sinusoidal components of arbitrary frequency, amplitude and phase. The component sinusoids are formed in segments of a predetermined period and modulated according to a preselected function. The modulation characteristic is compensated for by overlapped concatenation of adjacent segments.
