Surface Acoustic Wave Time-Base Correction Systems

Surface-wave acoustic delay lines are adapted to time-base correctors. The basic theory of operation is described. Particular emphasis is placed on the system design which employs the dispersive surface-wave delay lines. Of interest for the future are devices made by the same techniques and processes as used for the semiconductor industry. Surface-wave delay lines satisfy these criteria and therefore, future time-base correctors will no doubt be constructed of large blocks of integrated packages. Soon, time-base correctors with wider correction ranges and other desirable characteristics will be fit into a reasonably sized space at a reasonable cost.
