Claims

13. A DIGITALLY-VARIABLE LENGTH DELAY LINE CIRCUIT FOR PRODUCING A PHASE SHIFT IN AN A.C. SIGNAL PROPORTIONAL TO AN INPUT REFERENCE SIGNAL WHICH COMPRISES:

(A) A PLURALITY OF STRIP-LINE CONDUCTORS OF DIGITALLY-YINCREASING LENGTHS, (B) A SERIES OF DIODE SWITCHING MEANS FOR ALTERNATIVELY CONNECTING EACH OF THE CONDUCTORS IN A SERIES CIRCUIT OR SHUNTING THE CONDUCTOR TO RPOVIDE A DIGITALY-VARI-ARI ABLE LENGTH STRIP LINE, (C) A FLIP-FLOP CONNECTED TO OPERATE EACH DIODE SWITCHING MEANS, (D) CONTROL CIRCUIT MEANS FOR ACTUATING THE FLIP-FLOPS SEQUENTIALLY IN RESPONSE TO A CLOCK PULSE SIGNAL TO PROVIDE A DIGITALLY-INCREASING EFFECTIVE LINE LENGTH, (E) CONVERTER MEANS CONNECTED TO THE STRIP LINE FOR PRODUCING A FEEDBACK SIGNAL PROPORTIONAL TO THE EFFECTIVE LINE LENGTH, (F) A COMPARATOR CONNECTED TO THE OUTPUT OF THE CONVERTER MEANS FOR COMPARING SAID FEEDBACK SIGNAL TO A REFERENCE INPUT SIGNAL RELATED TO THE DESIRED PHASE ANGLE AND FOR PRODUCING AN OUTPUT SIGNAL WHEN THE REFERENCE INPUT SIGNAL EXCEEDS THE FEEDBACK SIGNAL BY A PREDETERMINED AMOUNT, AND (G) AN AND GATE CONNECTED AT ITS OUTPUT TO THE INPUT OF THE FLIP-FLOP AND CONNECTED AT ITS INPUTS TO THE OUTPUT OF THE COMPARATOR AND TO A CLOCK PULSE TER-E TERMINAL FOR PASSING CLOCK PULSES ONLY WHEN THE COMPARATOR PRODUCES ITS OUTPUT SIGNAL.
