ABSTRACT:
The present invention provides a system and method for using a single digzed component of an analog signal to be converted into a pair of digital signals used to re-establish the analog signal. A low level serial transceiver transforms a first analog signal into a first digital signal representing the complement of the first analog signal. The first digital signal is propagated through an electronic interface circuit such as a matrix switch or through some electronic circuit used to detect characteristics of the analog signal. In response to receiving the first digital signal, a logic circuit generates a second digital signal representing the analog signal, and also outputs the first digital signal. In response to receiving the first and second digital signals, a retimer generates a third digital signal comprising a series of pulses. Each of the pulses of the third digital signal is generated in response to the retimer determining that the first digital signal undergoes a positive voltage transition from one logic level to a higher logic level. The retimer also generates a fourth digital signal comprising a series of pulses. Similarly, each pulse of the fourth digital signal is generated in response to the retimer determining that the second digital signal undergoes a positive voltage transition from one logic level to a higher logic level. A second low level serial transceiver transforms the third and fourth digital signals into a second analog signal having substantially the same waveform as has the first analog signal.
