摘要

P DEVICE FOR RHYTHM RECOVERY24, 13 USED IN AN INFORMATION TRANSMISSION SYSTEM COMPRISING A CENTRAL STATION1 AND REMOTE STATIONS2, 3, 4, 5. EACH STATION HAS AT LEAST ONE TRANSMITTER CIRCUIT11, 21, 23, 31, 41, 51 AND A RECEIVER CIRCUIT12, 20, 22, 30, 40, 50. THE INFORMATION IS MULTIPLEXED TEMPORALLY IN THE SENSE CENTRAL STATION TO REMOTE STATIONS AND IS TRANSMITTED ACCORDING TO THE PRINCIPLE SAID AS AMRT IN THE OTHER DIRECTION. The clock H of the multiplex sense is used to set the frequency, in the direction A.M.R.T., of a first loop with a phase lock while a second loop provides a fast reset. THIS RHYTHM RECOVERY DEVICE CONSISTING OF THIS DUAL LOOP FULFALLY SATISFIED WITH PRECISION REQUIREMENTS AND RESIDUAL TRIGGER REDUCTION. / P P APPLICATION: RURAL TELEPHONY SYSTEMS. / P
