A circuit for power amplification for an audio amplifier that reduces power supply noise amplified to the load. The circuit takes the prior art circuit's existing output coupling cap and power supply decoupling cap and connecting them in series from the power supply to ground. The output of the amplifier is then directly coupled to the load and the other side of the load is connected at the &ldquo;null point&rdquo; between the two capacitors.

Power supply rejection circuit for an audio amplifier

A method of communicating from a transmitter to a receiver over a communication medium. For the transmitter, the method includes the step of formatting data into a data stream to be communicated across the communications medium. This data stream comprises a plurality of headers (PACK HEADER). Moreover, for each of the plurality of headers, the method performs two steps. First, the method modifies information encoded by the header by performing a bitwise logical operation between selected bits of the header (B) with a predetermined bit pattern (A). Second, the method transmits the plurality of headers on to the communications medium. For the receiver, the method includes the step of receiving the plurality of headers from the communications medium. Additionally, for each of the received headers, the receiver recovers the information encoded by the header.
