Abstract
An apparatus is described for the dual modulus prescaling of a high frequency signal. The apparatus comprises a dual modulus divider, second divider, synchronization circuit for providing a first modulus control signal to the dual modulus divider, and means for coupling the output of the second divider to the input of the synchronization circuit when a second modulus control signal is in a first state.
