Abstract
There is provided a jitter measurement apparatus to measure jitter of a signal under measurement. The jitter measurement apparatus includes a pulse generator that outputs a demodulated signal indicating the jitter of the signal under measurement, by outputting a pulse having a substantially constant pulse width in synchronization with each predetermined edge of the signal under measurement, a DC component detecting section that detects a DC component of the demodulated signal output from the pulse generator, and an adjusting section that adjusts the pulse width of the pulse output from the pulse generator, based on the DC component of the demodulated signal which is detected by the DC component detecting section.
