Title: Frequency synthesiser

Abstract: The present invention relates to a frequency synthesizer for generating an output signal (So) the frequency of which has a non-integer, fractional relationship of value Nn/Nd, where Nn and Nd are integer numbers, with respect to a frequency (fr) of an input signal (Sr). The synthesizer is characterized in that it comprises a device for multiplying by M, where M is an integer number, the frequency of the input signal in order to produce a high frequency intermediate signal (Si), and a device for dividing the frequency of this intermediate signal by (M.times.Nd)/Nn in order to generate the output signal (So).
