System for transmitting information pulses

Abstract

Abstract A PHASE COMPARISON DEVICE WHICH IS FEEDBACK TO CCOMPENSATE FOR DIFFERENCES IN THE PREDETERMINED PHASE RELATIONSHIP BETWEEN THE CLOCK PULSES AND THE CARRIER SIGNALS. A SYSTEM FOR TRANSMITTING INFORMATION PULSES COMPRISING A TRANSMITTER AND A RECIVER. THE TRANSMITTER COMPRISING A CARRIER GENERATOR, A MODULAR WHICH IS COUPLED THERETO AND ACLOCK PULSE GENERATOR. THE INFORMATION PULSES ARE SYNCHRONIZED WITH THE CLOCK PULSES, WHICH ALSO DETERMINE A FIXED PHASE RELATIONSHIP BETWEEN THE CARRIER SIGNAL AND THE CLOCK PULSES. THE CARRIER SIGNAL IS PHASE-SHIFTED MODULATED BYY THE INFORMATION SIGNAL. THE RECEIVER COMPRISES A CARRIER REGENERATOR AND A DEMODULATOR WHICH IS CONNECTED THERETO AND WHICH RECEIVES THE PHASESIFT MODULATED CARRIER SIGNAL. THE OUTPUT OF THE DEMODULATOR IS CONNECTED TO A CLOCK PULSE GENERATOR FOR DERIVING AMBIGUOUS CLOCK PULSES SYNCHRONIZED WITH THE CLOCK PULSES OF THE TRANSMITTER BY DETECTING ZERO PASSAGES OF THE DEMODULATED SGNAL. THEOUTPUT OF THE CLOCK PULSE GENERATOR IS CONNECTED TO
