摘要：
A filter circuit comprises a plurality of sampling and holding circuits for sampling and holding analog input signal with a predetermined sampling period, a calculation circuit for multiplying each the analog input signal by a predetermined multiplier, and for summing the multiplication results. The sampling and holding circuits are controlled in an electrical power such that the electrical power is decreased when holding.
