ABSTRACT:
The invention relates to a device and a method for converting a digital signal having a plurality of data-bits into a filtered analog signal. A device according to the invention includes a delay element arranged to produce one or more differently delayed version of the digital signal and a digital-to-analog conversion circuitry arranged to convert the digital signal and the one or more differently delayed, and possibly differently scaled, versions of the digital signal into analog signals and to produce the filtered analog signal as a combination of the analog signals. Therefore, the device constitutes not only a digital-to-analog-converter but also a finite impulse response filter.
