Really a clever idea. Thanks also to Zim for the pointer to the Chinese Remainder Theorem. Klaus, do you have any document that explains how to choose the three prime numbers used for the length of the sin/cos tables, and how to compute the phase increment for each, as a function of the wanted output frequency. Thanks. 73 Alberto I2PHD
