摘要： The present invention aims at providing a sampling filter capable of changing a filtering characteristic without use of a complicate waveform as a control signal. A sampling filter 100 has a control section 140, a plurality of integrators, and a plurality of switches. An input current is accumulated in a plurality of capacitors in one clock; adds up electric charges accumulated in the integrators in several preceding clocks to one preceding clock; and outputs a result of addition. When electric charges are accumulated in the integrators in each clock, output electric charges can be subjected to, while being weighted, addition by switching an electric current to be input, so that the filtering characteristic is changed.
