ABSTRACT:
A filter has a plurality of series circuits each including a reactance element and a switching element and the series circuits are connected in parallel. The switching elements are driven by clock pulses of the same period. When the switching elements are driven simultaneously, information stored in the reactance elements is cleared, whereby the filtering band can be switched over at high speed.
