Abstract
A modulation processor () comprises a first processing stage () and a second processing stage (). The first processing stage () comprises a phase generation stage () arranged to generate a phase signal (PM) indicative of a phase of a modulation signal (S), a differentiation stage () arranged to generate a frequency signal (FM) by differentiating the phase signal (PM), and a first bandwidth reduction stage () arranged to generate a first output signal (FM_LP) by reducing a bandwidth of the frequency signal (FM). The second processing stage () is arranged to generate a second output signal (AM*) proportional to the modulation signal (S) with its phase retarded by an angle equal to an integral of the first output signal (FM_LP).
