Abstract:
A time interval analyzer includes a phase comparator which decides whether a measured signal contains a delay quantity for either a positive delay or a negative delay relative to a characteristic value, and a processor circuit which outputs a ratio of a number of the measured signals containing the positive delay and a number of the measured signals containing the negative delay.
