Abstract

Apparatus and method for shifting the frequency range of an audio frequency range signal using digital frequency shifting and single sideband amplitude modulation techniques. In one embodiment, the audio signal (2) is shifted to an ultrasonic frequency range utilizing digital signal processing techniques in which an audio frequency signal is frequency shifted by modulation to a carrier frequency and in which a single sideband modulated signal (6) is formed.
