System for phase aligning parallel signal processing channels
TL;DR: In this paper, a system for automatically phase aligning parallel signal processing channels such as those used in the receiving system of monopulse radars was proposed. But the phase alignment was not considered.
Patent
Microwave speed meter
TL;DR: A meter for measuring the relative velocity of an object, including a diplexer for illuminating the object with a beam of microwave energy and for developing from energy reflected from the object a difference signal having a frequency which is proportional to the relative velocities of the object, a phase-locked loop for synchronizing the frequency of an internal oscillator with that of the difference signal, a lock signal when synchronization is achieved, a reset signal from the lock signal and a latch signal a predetermined period thereafter, a circuit for counting the cycles of the internal oscillators which are developed
Patent
Accurate and stable encoding with low cost circuit elements
TL;DR: In this paper, a phase-locked frequency multiplication network is proposed for analog-to-digital conversion, where the network output frequency is a harmonic of the frequency of the reference signal.
Patent
Phase-locked loop in which frequency divider ratios are altered to obtain rapid lock-in
TL;DR: In this paper, a phase-locked loop for maintaining a voltage-controlled oscillator within the locked-in range by means of excess pulse detectors provided for both high or low frequency deviations which function to significantly alter the dividing ratios of the dividing circuits respectively coupled to the voltage controlled oscillator and the standard signal oscillator.
Patent
Phase and frequency comparator for signals unavailable simultaneously
TL;DR: In this paper, a phase and frequency comparator for input signals unavailable simultaneously includes a channel for each of the signals, each channel having a wave shaper for providing a square wave corresponding to the signal, a storage counter driven by the wave shifter, and an oscillator driven by a single oscillator connected in feedback relation to the counter, with means provided for thereupon rendering the oscillator output frequency constant.
