Experiments on frequency mixing show that up and down conversion is enhanced over results reported for lithium niobate alone. Convolution experiments with a transverse electrode configuration show a similar enhancement. In addition, it is shown that one may represent the convolver with a load‐independant voltage element in the linear response region; but when saturation begins, this source becomes dependent on load current. Experiments are reported which demonstrate how one signal may be used to vary the attenuation of another.
