Abstract
Aspects of the disclosure include an apparatus that has a first clock generator and a second clock generator. The first clock generator is configured to drive a first circuit, causing the first circuit to (i) receive a signal corresponding to an audio input, and (ii) determine whether an energy level of the signal exceeds a predetermined threshold. The second clock generator is activated when the first circuit determines that the energy level of the signal exceeds the predetermined threshold. The second clock generator is configured to drive a second circuit, causing the second circuit to determine whether the signal matches a predetermined pattern. A third circuit is activated when the second circuit determines that the signal matches the predetermined pattern.
