CONVOLUTION AND CORRELATION IN REAL TIME WITH NONLINEAR ACOUSTICS

We propose a method for obtaining the convolution, and correlation, of signals in real time through the nonlinear interaction of two acoustic waves in ferroelectric crystals. The experimental results presented here for the convolution of two 1350‐MHz signals indicate that the strength of the interaction is sufficient to provide new signal processing devices.
