Abstract
A gate circuit is configured to output a received signal via a buffer amplifier, enter the output in a storage capacitor via a first switching circuit normally taking its off-position, compare the signal levels at both ends of the switching circuit and feed back the comparison result to an input terminal via a second switching circuit normally taking its on-position, and configured so that when noise components in the received signal are detected, a control signal is produced to change the first switching circuit to its on-position and the second switching circuit to its off-position.
