Abstract
One embodiment described herein includes a method for transmitting a signal. The method includes generating a Manchester encoded data stream and combining the Manchester encoded data stream with an amplified clock signal to produce an amplitude modulated signal having a zero crossing at each edge of the amplified clock signal. The amplitude modulated signal can then be sent over a communication medium.

A method for transmitting a signal, the method comprising:
- generating a Manchester encoded data stream;
- combining the Manchester encoded data stream with an amplified clock signal to produce an amplitude modulated signal having a zero crossing at each edge of the amplified clock signal, wherein combining the Manchester encoded data stream with an amplified clock signal includes subtracting the voltage of the Manchester encoded data stream from the voltage of the amplified clock signal;
- and
- sending the amplitude modulated signal over a communication medium.
