Abstract
An acoustic wave storage convolver includes a plurality of sampling transducers coupled to a surface wave propagating medium along a path defined by a pair of opposedly disposed input transducers. The sampling transducers, each of which is connected to a suitable signal storage element, are equally spaced along the path by an integral number of acoustic wavelengths plus or minus 1/4 wavelength for providing successive samples of surface waves propagated along the medium in phase quadrature relationship. Means initiating the signal storage function and output means developing the convoluted product of two high frequency signals applied to the input transducers are provided.
