Abstract
A digital-to-analog conversion system comprises a digital input, a digital-to-analog converter and a modified digital signal generator. The digital-to-analog converter has a conversion frequency and is subject to a periodic error having a periodicity equal to that of an N-th sub-harmonic of the conversion frequency, where N is an integer. The digital input is operable to receive a digital input signal. The modified digital signal generator is interposed between the digital input and the digital-to-analog converter and is operable in response to the digital input signal to generate a modified digital signal. The modified digital signal comprises a dynamic digital mitigation component that mitigates the periodic error of the digital-to-analog converter.
