Abstract : The patent relates to a composite transducer for use in acoustic correlators and convolvers, useful, for example, for decoding pulse-type signals. When the combination of a stream of pulses in one propagation channel and the coding in that channel matches the combination of the stream of pulses and the coding in another channel, that is, when there is correlation between the two combinations, a maximum output is obtained; otherwise an output signal of a much smaller magnitude is obtained.
