Abstract

A method, system or program product for generating a sine waveform and a cosine waveform is provided by providing in a first look-up table (24) data corresponding to quantized values of a portion of the period of a cosine waveform and providing in a second look-up table (25) data corresponding to quantized values of a portion of the period of a sine waveform corresponding to the period of the cosine waveform quantized values from both the first (24) and the second (25) look-up tables may be to generate a sine waveform. Furthermore, quantized values from both the first (24) and the second (25) look-up tables may also be utilized to generate a cosine waveform.
