System and method for modulating a carrier frequency










Image Number 9 for United States Patent #5592131.

A carrier frequency modulating system and method for producing a modulated carrier frequency is disclosed. The system comprises a carrier frequency signal generator for producing a carrier frequency signal at a carrier frequency at an output thereof. The system further comprises a sequencer for producing a modulation signal at an output thereof. This modulation signal comprises a plurality of modulation signal portions separated by at least one null modulation signal portion having a corresponding time length. The system is provided with a modulator for producing a modulated carrier frequency signal at an output thereof. The modulator has a first input connected to the output of the carrier frequency signal generator for receiving the carrier frequency signal, and has a second input for receiving the modulation signal. The system further comprises a power supply unit for supplying electrical power to the carrier frequency signal generator. The sequencer is connected to the carrier frequency signal generator for controlling the activation thereof and to interrupt the carrier frequency signal generator instead of modulating the null modulation signal portion during the corresponding time length, whereby power consumption of the system is minimized.
