Abstract
The present invention relates to a system and method for digitally compensating signal converters and in particular a digital to analog converter which receives digital input data for a digital to analog converter and supplies anti-function digital coefficients derived from the error function of the digital to analog converter and corresponding to the digital input data and applies the anti-function digital coefficients to the digital input data to pre-condition the digital input data to compensate for the error function of the digital to analog converter. The invention also extends to analog to digital converters.
