Abstract
In a filter in which, in order to obtain the desired filter characteristic, a weighted sum of different signals is formed, it is proposed in accordance with the invention that for the formation of said sum means are employed which are constituted by capacitor circuits, which during a first time interval are each charged by said signals, and by a connection circuit for the formation, during a second time interval, of the equivalent of a single capacitor across whose plates the weighted-sum signal appears. The invention is used for the filtration of sampled analog signals.
