Claim:
1. A digital amplifier for providing a desired electrical output power, the amplifier comprising: a power source for generating the electrical output power, a digital input adapted for receiving a digital input signal, the digital input signal representing a desired electrical output power level, a reference power generator for generating an analogue, reference power controlled by the digital input signal, a power measurement component adapter for measuring the power differential between the electrical output power provided by the power source and the analogue reference power, an analogue-to-digital converter adapted for converting the power differential into a digital power differential value, a combiner adapted for providing a combined digital signal by adding, the digital power differential value to a signal including at least the digital input signal to the reference power generator for generating the analogue reference power, wherein the power source is adapted for providing the electrical output power corrected for the difference between a power value indicated by the digital input signal and the combined digital signal.
