DIGITAL LOGIC FREQUENCY CONTROL LOOP FOR MULTIVIBRATOR COMPOSED OF TWO MONOSTABLE ELEMENTS

摘要

Servo-controlled frequency multivibrator composed of two monostable elements looped together comprising a first and second digital element controlling respectively a first and second logic gate ensuring in the one case the synchronous starting of the multivibrator on the pilot frequency F and in the other case the blocking thereof and a servo-control regulating circuit for the polarization voltage of the monostable elements, sensitive to the comparison between the end of the mth pulse having a frequency F and of the nth pulse having a frequency of f of the multivibrator, m and n being chosen so that m/F = n/f.
