Abstract
The tuning circuit for a t.v. receiver frequency synthesis has a group of inputs for application of channel data obtained by a convertor form a program selection unit. The relation between the selected program and channel datum is applied to one of the inputs which is visible. The convertor comprises a combination of switches so arranged that the above relation is visible from the position of switches. Each of the program exchange switches has two contacts (53, 55), so that two conductor leads (57, 59 61, 63) are connected with a nodal point on a converter matrix.
