Abstract
A digital baseband signal for radio frequency transmission is processed prior to performing digital-to-analog conversion. The digital baseband signal is filtered. The number of bits of the digital baseband signal is reduced to minimise the size of the digital-to-analog converter. By performing some of the bit reduction before filtering, the size of the filter circuit is reduced whilst still meeting relevant performance parameters.
