An electrical filter circuit for processing analog sampling signals consists of N+1 capacitors interconnected to cyclically circulate N signal charges, the capacitors all being of approximately the same size, and interconnected with an operational amplifier. A plurality of switches are employed, controlled by a clock signal having N+1 phases. Phase controlled switches supply an input signal to the input of the operational amplifier, and provide an output from the filter circuit.
