ABSTRACT:
By measuring the waveform of the reflected wave obtained by transmitting a pulse to an open-ended transmission line, a transfer function of the transmission line with respect to the incident wave is computed as a result of the measurement. Then, the waveform of the output wave at the output end or the open end of the transmission line is estimated in response to an individual input signal by using the transfer function computed. The transmission delay time of the transmission line is obtained by computing the time difference between the transient timing of the estimated waveform of the output wave and the transient timing of the waveform of the input signal.
