Abstract
The invention discloses a transmitter () comprising a pulse encoder () for creating pulses from the amplitude of an input signal to the transmitter, a compensation signal generator () for cancelling quantization noise caused by the pulse encoder (), a mixer or I/Q modulator () for mixing an output of the pulse encoder with the phase of an input signal to the transmitter and an amplifier () for creating an output signal from the transmitter. In the transmitter (), a control signal (CA) for controlling a function of the amplifier () comprises an output signal from the compensation signal generator (), and an input signal to the amplifier () comprises an output from the mixer () having been modulated () to a desired frequency.
