  • Alternate pulse inversion encoding scheme for serial data transmission
    Patent number: 4897854
    Abstract: A method is provided for encoding and decoding data to be transmitted over a communication network via transformer coupling. The data is pulse width modulated, and split into separate first and second data streams containing alternate pulses. The first data stream is inverted, and recombined with the second data stream to produce a pulse width modulated bi-polar data signal having an alternating pulse sequence. The data is decoded at the receiver by inverting the pulses of one polarity, and combining them with the pulses of the other polarity to form a pulse width modulated data stream.
