Receiver and transmitter of a frequency-modulated signal

Abstract

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.
