A method and apparatus for generating digitally modulated signals in which a serial data stream of digital signals to be modulated ( ) is provided, the serial data stream being converted into real and imaginary components ( ) which are then converted into a complex polar signal ( ) representing the serial data stream. A carrier of appropriate frequency is generated by an infinite impulse response filter ( ) and the polar signal is mixed with the output of the infinite impulse response filter to provide a representation of the complex polar signal modulated at the frequency generated by the infinite impulse response filter ( ). Subsequently the imaginary component of the resulting representation is stripped from the signal ( ) and the real component of the resulting representation is applied to a digital to analog converter ( ) to produce an analog version of the serial data stream.
