Abstract
A charge transfer transversal filter, wherein an input signal to the filter is branched off; an electric charge is generated in a semiconductor substrate according to each branch of the input signal supplied thereto; the electric charge is so weighted as to cause the filter to have a desired frequency characteristic; an electric charge thus weighted is introduced into a potential well of one delay means of a charge transfer device to be added to the electric charge transferred to the well from the preceding delay means; and the resultant mixture of electric charges is transferred through the charge transfer device.
