Equalising methods flatten DAC frequency response

Posted: 13 Feb 2013 ?? ?Print Version ?Bookmark and Share

Keywords:Digital-to-analogue converters? DC? fS/2?

Digital-to-analogue converters (DACs) convert digital data to analogue voltage or current in applications such as instrumentation and wireless communications. A DAC's output frequency generally ranges from DC to less than fS/2, where fS is the input-updating frequency. The output frequency response for most DACs, however, rolls off according to the sin(x)/x (sinc) frequency-response envelope.
