Patent ID: 8463256

Claim:
A system comprising: a communication apparatus; a test subsystem configured to initiate an audio test of the communication apparatus, wherein the test subsystem is configured to receive, in response to the audio test, a set of audio test data at a predetermined constant data rate, and wherein the communication apparatus is configured to alternately enable and disable the output of the set of audio test data during the audio test; and a converter coupled to receive the set of audio test data output from the communication apparatus; wherein the communication apparatus includes a radio frequency (RF) circuit coupled to a digital processing circuit, wherein the digital processing circuit is configured to enable the output of the set of audio test data during inactive periods of operation of the RF circuit and to disable the output of audio test data during active periods of operation of the RF circuit; and wherein the converter is configured to provide the set of audio test data to the test subsystem at the predetermined constant data rate during the active and inactive periods of operation of the RF circuit.
