摘要： A bus communication transceiver measures a delay time in response to a rising time of a signal and adjusts a falling waveform of the same signal based on the measurement result. A signal waveform, especially, a duty ratio can be adjusted in a predetermined standard range. Also, the bus communication transceiver realizes an excellent real-time operation, without receiving influence of a variation of the voltage supplied to the bus, and a variation of a total of loads connected with the bus. The bus communication transceiver measures the delay time by using the signal and adjusts the waveform of the signal.
