ABSTRACT:
A surface-wave filter that has a variable transmission band is formed of at least two parallel tracks having input and output transducers whereby the bus-bars of one transducer of one track lie at two different potentials and one bus-bar of one transducer of a further track lies at one of the two potentials. The other bus-bar is selectively connectable to the other of these potentials so that the transducer of the further track is selectively enabled or disabled. Since the tracks have different transmissions bands, the transmission band of the filter is thus, selectable by connecting and disconnecting the further track.
