Patent ID: 8208586

Claim:
A jitter measuring apparatus comprising: a jitter demodulator which demodulates a jitter component of a digital signal input from the outside; a jitter amount detector which detects the amplitude value of a demodulation signal output from the jitter demodulator; a display unit for displaying the value detected by the jitter amount detector; an interpolator which measures a period of the demodulation signal output from the jitter demodulator and interpolates the demodulation signal processing with a rate corresponding to the measured period; a display control section which displays on the display unit the value detected by the jitter amount detector and a waveform of the demodulation signal interpolated by the interpolator; and a housing, wherein the jitter demodulator, the jitter amount detector, the interpolator, and the display control section are contained in the one housing, and the display unit is mounted on an outer surface of the housing.
