Patent ID: 7868804

Claim:
A method for performing one of emphasizing and de-emphasizing of an analog data signal comprising: receiving a data signal, the data signal being indicative of bit values of binary data and including two half rate data signal portions; using a main analog driver, converting the data signal into a first analog data signal; determining a second data signal by delaying the data signal a predetermined time interval and inverting the delayed data signal; using a de-emphasis driver, converting the second data signal into a second analog data signal, wherein the second analog data signal is additive to the first analog data signal if the data signal and the second data signal are indicative of a same bit value, and wherein the second analog data signal is subtractive to the first analog data signal if the data signal and the second data signal are indicative of an opposite bit value; and, performing one of emphasizing and de-emphasizing of the first analog data signal by superposing the first analog data signal and the second analog data signal and multiplexing the two half rate data signal portions into a full rate data signal.
