"Contract supervisors: D.B. Wohlberg, S.M. Chow." "August 12th, 1974." Digitized edition from print [produced by Innovation, Science and Economic Development Canada]. Includes bibliographical references. "This report presents an overview of the principles of surface-wave devices important in signal-processing applications. The fundamental properties of surface-waves are reviewed and currently practical components for use in radar systems, spread-spectrum communications systems, and bandpass filtering are described. The main emphasis is on dispersive and non-dispersive delay lines, devices for generating and detecting various waveforms, and methods for generating and detecting fixed and programmable biphase codes. The discussion of new devices includes multistrip couplers, oscillators, long delay lines, surface-wave convolvers and amplifiers, reflective array structures, and devices using overlay films. The properties of substrate materials and current fabrication methods of importance in device design are covered in considerable detail. Performance specifications of current operational components are included throughout the report"--Abstract, page i. Acoustic surface wave devices Adler, E. L., author. Canada.
