Abstract
The present invention relates to a device () and a method for encoding an input signal () into a digital pulse-width and/or phase modulated output signal (). The present invention also relates to a transmission method, a power amplifier and a transmitter. With the aid of a mapping process comprising at least three-stages, a sequence of output pulses () is generated which corresponds on average over time to a theoretical, previously computed target pulse. In this way, the device () or the method can be digitally implemented and a large part () of the device () can also be operated at a clock rate that is substantially lower than a clock rate of the output signal generator ().
