Abstract :
The convolution of two 12-MHz contradirected surface-acoustic wave signals on barium titanate has been observed. Overall conversion losses in the signal processing were approximately 60 dB. A 3-6-dB enhancement of convolved signal amplitude was achieved by the application of an external polarizing field to the output electrodes.
