ABSTRACT:
A digitally compensated modulation system for frequency synthesizers has a single modulation input line with flat frequency response to zero hertz. The above is accomplished while eliminating circuit components and adjustments by integrating reference oscillator temperature compensation, modulation compensation for changes in the voltage controlled oscillator modulation sensitivity and modulation compensation for changes in the reference oscillator modulation sensitivity. Signals requiring modulation enter a microprocessor and are summed together with a microprocessor generated signal and a temperature compensation input to create a composite modulation signal. The composite modulation signal is then multiplied by appropriate constants and sent to the synthesizer.
