Abstract
A method for converting a digital signal to an analog signal, said method including a plurality of signal sources, preferably current sources, one or more of said signal sources being variable output signal magnitude sources, said method including the steps of setting the output signal magnitudes of the one or more variable output signal magnitude sources by individual setting signals being input signals for said respective variable output signal magnitude sources, wherein said conversion is adaptable on a per signal basis in response to needs concerning bandwidth and/or accuracy for achieving a trade-off between sample-rate and resolution of said conversion.
