Patent attributes
A transmission apparatus includes a waveform processing circuit. The waveform processing circuit is configured to receive a modulated signal indicating each of values of pulses by one of four signal levels including first, second, third, and fourth signal levels ascending in this order. The waveform processing circuit is configured to output a signal corresponding to the modulated signal. A portion of the output signal corresponding to a portion of the modulated signal that transitions between the first and fourth signal levels, transitions between a first adjusted signal level different from the first signal level and a second adjusted signal level different from the fourth signal level. The transmission apparatus is configured to transmit a signal corresponding to the signal output from the waveform processing circuit through a wired communication path.
