ABSTRACT:
A frequency synthesizer circuit operates in a time shared mode. Thus the frequency synthesizer circuit operates to transmit and/or receive a particular frequency for a chosen small amount of time and then sequentially transmits and/or receives the other frequencies for chosen small amounts of time. After all the chosen frequencies have been transmitted and/or received the synthesizer circuit will return to the first of frequency and begin to repeat the process in cyclical fashion.
