Abstract :
A new method for generating a low-distortion n-tone signal is presented. The new method uses a RAM based DDS generator, a frequency converter and a distortion monitor. The signal distortions are cancelled by using digital feedback, or re-writing RAM data recursively. Two feedback algorithms are presented for different configurations
