Device for generating a frequency modulated signal










Image Number 4 for United States Patent #4590445.

A device for generating a frequency-modulated signal according to a predetermined modulation law includes a digital generator that, from a clock signal, generates an output signal s(t) and a error signal (S.sub.e). The signal s(t) is a signal in which the duration of each alternance is an integer multiple of the clock period. The error signal (S.sub.e) represents the modulation errors of the output signal s(t) with respect to the theoretical output signal (S.sub.t) modulated according to the predetermined law. An error correction device receives the output signal s(t) and is controlled by the error signal (S.sub.e) and corrects the modulation errors and provides a corrected output signal.
