Abstract: A digital demodulator for angle-modulated (PM, FM) signals comprises:

an input module (1, 2) for generating, starting from the modulated signal (s fm ), a first component (cosφ(n)) and a second component (sinφ(n)) in quadrature with respect to one another, said components in quadrature being representative of the real part and of the imaginary part of the modulating signal (s'(t); s"(t)) represented as a complex variable; and
a processing module (4) able to generate an output signal, calculating the arctangent function of the ratio between said imaginary part and said real part, the output signal identifying the demodulated signal (s'(t); s"(t)).

The processing module (4) acts on the components in quadrature either directly, in the case of phase demodulation, or indirectly, in the case of frequency demodulation. In the latter case, the above-mentioned real component and imaginary component are calculated, respectively, as the sum of the products of each of the components in quadrature with a corresponding delayed version, and as the difference of the cross products of each of the two components in quadrature with a version delayed in time of the other component in quadrature.
The demodulator may be implemented either as a dedicated hardware unit, or else resorting to a computer program product for DSP or microprocessor.
