This report is the second Interim Technical Report on the contract. It covers research done on acoustic surface wave devices during the six month period 1 May to 31 October 1974. The objective of the research is the generation of new device concepts and the analytical and experimental verification as to their ultimate usefulness for signal processing applications. Improvements were made in acoustic surface wave convolver efficiency. The surface wave convolver can be used for performing convolutioncorrelation, time reversal and Fourier analysis of arbitrary signals. A new approach which may lead to low cost, simplified analogdigital conversion has been devised. This combines a surface acoustic wave delay line and external digital circuitry.
