In. Gurevich et Ya. Nikitin, CONTROLLABLE DELAY DEVICES IN 2-LEVEL FREQUENCY-SYNTHESIS SYSTEMS, Telecommunications & radio engineering, 48(5), 1993, pp. 61-68
A comparative analysis of controllable delay devices based on the conv
ersion of a digital control code into a voltage (current) and then int
o a time interval is given. The requirements imposed on the components
of the structures are formulated, theoretical relations are obtained,
and recommendations on their use are given.
