ABSTRACT:
A sampling circuit system enhances sampling resolution without increasing frequencies of clock signals for sampling. An input waveform is input to a first group of sampling circuits and a sampling circuit serving as a standard circuit. Clock signals out of phase from each other by 2 .pi.
(n=an integer not less than 3) radian, respectively, against a clock signal input to the standard circuit are input to the first group of sampling circuits for sampling. Then sampling signals output from the first group of the sampling circuits are input to a second group of sampling circuits so as to be sampled again by inputting a sampling signal output from the standard circuit as a common clock signal for the second group of sampling circuits.
