  • Amplification system, carrier tracking systems and related methods for use in parametric sound systems
    Patent number: 9036831
    Abstract: A signal processing system for generating an ultrasonic signal from an audio signal comprises a compressor, operable to compress the audio signal, and an equalization circuit, operable to equalize the audio signal. A modulation circuit is operable to combine the audio signal with a carrier signal to produce at least one modulated carrier signal. A voltage detection and control circuit is operable to: detect a voltage of the modulated carrier signal; compare the detected voltage of the modulated carrier signal to a desired voltage; and cause the voltage of the modulated carrier signal to be adjusted if the compared voltage differs by a predetermined amount from the desired voltage.
