Abstract
The invention relates to a signal generator with programmable variable frequency and comprises a reference oscillator, a first frequency divider receiving the signal emitted by the reference oscillator and delivering an instantaneous frequency signal (FS). A control chain for said first frequency divider comprises a second frequency divider and a first programmable integrator system, which controls the first frequency divider. A control chain for the second frequency divider comprises a second integrator system receiving the output signal (FS). This signal has an instantaneous frequency of the polynomial form ##EQU1##
