Abstract
A two-modulus variable frequency-divider circuit comprises a variable frequency-divider, a plurality of .div.2 frequency-dividers succeeding the variable frequency-divider, and a monitor. Outputs of one or more of the .div.2 frequency-dividers are coupled to the monitor which develops a monitor output determined by the states of the .div.2 frequency-divider outputs applied thereto. The monitor output is fed back to the variable frequency-divider as a frequency dividing factor setting signal. The two-modulus variable frequency-divider circuit is further provided with a signal converting circuit having a signal inverting function, which can selectively invert, in accordance with an externally applied control signal, the output of the two-modulus variable frequency-divider circuit or the output of the final one of those .div.2 frequency dividers which provide the outputs thereof to the monitor.
