Pulse regenerating repeater
Abstract
Abstract A PULSE REGENERATING REPEATER TO BE INSTALLED IN CASCADE IN A TRANSMISSION LINE TO REGENERATE ATTENUATED PULSES WHEREIN THE REPEATER CONSISTS OF A SERIES CONNECTION OF A WAVE REGENERATING CIRCUIT, A DELAY LINE AND A REFLECTING CIRCUIT RESPECTIVELY. AN ATTENUATED AND PHASE JITTERED INOPUT PULSE IS REGENERATED BY THE WAVE REGENERATING CIRCUIT AND THEN PROPAGATED ON THE DELAY LINE AND THE PORTION OF THE REGENERATED PULSE WHICH IS ABOVE A PRESELECTED CRITICAL VALUE OF THE REFLECTING CIRCUIT IS PASSED THERETHROUGH FOR TRANSMISSION AND THE REMAINING PORTION BELOW THIS CRITICAL VALUE IS REFLECTED TO FORM A TIMING PULSE WHICH IS SHUTTLED BACK AND FORTH ON THE DELAY LINE. THE SIMULTANEOUS PRESENCE OF AN INPUT PULSE AND A TIMING PULSE AT THE WAVE REGENERATING CIRCUIT TRIGGERS A NEGATIVE RESISTANCE DEVICE THEREIN, WHEREBY THE PULSE IS REGENERATED SUCH THAT THE RETIMING OF THE REGENERATED PULSE IS CONTROLLED AT THE ORIGINAL FUNDAMENTAL FREQUENCY BY THE TIMING PULSE.
