METHOD OF MANAGEMENT OF THE FREQUENCY CONTROL OF A TRANSMITTER RECEIVER AND OF THE PROGRAMMATION OF THE PROGRAMMABLE COUNTER OF HIS DIGITAL FREQUENCY SYNTHESIZER

摘要

A frequency synthesizer for a transmitter-receiver includes a variable frequency divider which is programmed by coded information supplied by a display device through a code conversion circuit constituted by memories, the contents of said memories not utilized for programming the divider being utilized for programming the control information which permits, through suitable decoder circuits, the direct control of the devices producing the different functions of the transmitter-receiver.
