Investigation of digital systems of phase locking with a delay in the control circuit

B. V. Sultanov


The relationships have been derived defining the conditions of local stability of digital systems of phase locking with a delay in the control circuit. The principles of calculation of such systems with a prescribed duration of transient process are developed.
