Abstract

Communications systems typically have a lim- ited bandwidth in which to transmit voice informa- tion. The audio frequency range of such voice infor- mation is generally limited to bandwidths of300 Hz to 3 kHz. Acoustic couplers, e.g. loud speakers and microphones, are used to enunciate the voice from audio signals output to the speaker or to generate audio signals from a voice input to a microphone.
