Abstract
A direct digital waveform synthesiser with DAC error correction includes a digital to analog converter system for producing a desired output waveform and having between its digital and analog output a characteristic having a linear component and a non-linear component; and a phase to amplitude converter including a storage device responsive to phase inputs to provide to the digital to analog converter system amplitudes modified to compensate for the non-linear component of a characteristic of the digital to analog converter system.
