Circuit for converting a train of duration modulated periodically recurring pulses to a train of similarly modulated periodic pulses having a different frequency of recurrence

Claim 1

A FREQUENCY CONVERTER COMPRISING: A CYCLIC BISTABLE SIGNAL SOURCE HAVING A PREDETERMINED FREQUENCY AND A VARIABLE RATIO BETWEEN FIRST AND SECOND STABLE STATES IN ONE CYCLE OF SAID SIGNAL; A CYCLIC BISTABLE CONTROL SIGNAL SOURCE HAVING A FREQUENCY WHICH IS SUB-MULTIPLE OF SAID CYCLIC BISTABLE SIGNAL SOURCE AND HAVING FIRST AND SECOND STABLE STATES OF EQUAL DURATION; MEAN RESPONSIVE TO THE FIRST STABLE STATE OF SAID CONTROL SIGNAL SOURCE AND THE SUB-MULTIPLE NUMBER OF THE FIRST STABLE STATE OF SAID CYCLIC BISTABLE SIGNAL SOURCE FOR DEVELOPING AN ANALOG SIGNAL PROPORTIONAL TO THE SUM OF THE DURATIONS OF SAID SUB-MULTIPLE NUMBER OF FIRST STABLE STATES OF SAID CYCLIC BISTABLE SIGNAL SOURCE; AND MEANS RESPONSIVE TO SAID ANALOG SIGNAL AND THE SECOND STABLE STATE OF SAID CONTORL SIGNAL SOURCE FOR PRODUCING A BISTABLE SIGNAL HAVING FIRST AND SECOND STABLE STABLES OF THE SAME RATIO OF SAID CYCLIC BISTABLE SIGNAL SOURCE AT SAID SUB-MULTIPLE FREQUENCY.
