The receiver of the invention consists of a non-baseband component ( 1 ), a frequency demodulator ( 3 ), and a baseband component ( 5 ). The non-baseband component ( 1 ) causes a first group delay variation in a frequency-modulated non-baseband signal while processing the non-baseband signal. The first group delay variation in the frequency modulated non-baseband signal results in a second group delay variation in the demodulated baseband signal. The baseband component ( 5 ) is able to substantially compensate the second group delay variation in the demodulated baseband signal. The transmitter of the invention consists of a baseband component ( 21 ), a frequency modulator ( 23 ), and a non-baseband component ( 25 ). The baseband component ( 21 ) is able to cause a first group delay variation in an unmodulated baseband signal. The first group delay variation in the unmodulated baseband signal results in a second group delay variation in the frequency-modulated nonbaseband signal. The non-baseband component ( 25 ) for processing the frequency-modulated non-baseband signal has a certain group delay characteristic. This certain group delay characteristic is substantially compensated by the second group delay variation.
