Abstract
A voltage controlled oscillator in a phase locked loop generates signals through the avionics communication band, and the VCO output is divided alternately by first and second factors corresponding to kilohertz range increments, and then by a third factor corresponding to the applicable megahertz increment. The relative time periods during which the respective KHz factors are utilized depends upon the count generated by a logical circuit, operating responsively to encoded representations of channels to be utilized. First and second preloaded counters operate for a predetermined time period, during which both factors are utilized alternatively; during the remainder of the counting cycle, only one factor is utilized.
