Abstract
A two-track convolver has input transducer assemblies at each end of integrated electrodes. Each of the input transducer assemblies is formed of two individual transducers which are connected in series. One of the transducer input assemblies connects to an input signal and the other of the input assemblies connects to a reference signal. Transducers which are diagonally arranged with respect to the two integration electrodes connect to reference potential. For a given input impedance, the system permits a greatest possible chirp duration corresponding to a large length of the individual transducers.
