Abstract
A delay circuit for producing in an electrical circuit a time delay. The circuit includes a pulse generator which produces an edge at a given time interval after an edge is applied to its input. The time interval can be adjusted so that it automatically follows a reference time interval such as a clock period. The circuit has application in the read circuitry of digital tape devices.
