Combined acoustic surface wave and semiconductor device particularly suited for signal convolution |
摘要 |
The disclosure relates to a novel device for performing signal convolution functions such as auto and cross correlation through the use of combined acoustic surface wave and semiconductor devices. A detector or pickup unit comprising a plurality of interdigital fingers coupled to associate semiconductor diodes is disposed on the surface of an acoustic substrate in the path of surface waves propagated along the surface of the substrate. The diodes are operatively connected to a summing bus from which an output signal indicative of some characteristics of the surface waves may be obtained.
