Transmission delay analytical device, transmission delay analysis program and transmission delay analytical manner

摘要

A transmission delay analyzing apparatus includes: a first acquisition section that acquires a noise waveform from among waveforms which propagate in a first transmission line and acquired by a receiving circuit; a first calculation section that calculates a noise peak level (Vnf) which is the peak level of the noise waveform acquired by the first acquisition section; a second acquisition section that acquires a signal waveform (VIL - Vnf) free from noise from among the waveforms which propagate in the first transmission line and acquired by the receiving circuit; and a second calculation section that calculates a delay variation (tpd) of a transmitted signal based ON the signal waveform acquired by the second acquisition section and a threshold (VIH) for determining the level of a signal that the receiving circuit has received from the first transmission line and the noise peak level (Vnf) calculated by the first calculation section.
