The tasks included investigation of surface acoustic wave generation techniques as well as the study of surface wave propagation on the ZnOSi surface. The structures were used to prepare a sequence generator and its reciprocal matched filter to experimentally demonstrate the generation and correlation of a biphase sequence.
