Pulse-amplitude modulation — Principle of PAM: (1) original signal, (2) PAM signal, (a) amplitude of signal, (b) time Pulse amplitude modulation, acronym PAM, is a form of signal modulation where the message information is encoded in the amplitude of a series of signal… … Wikipedia
Time-domain reflectometer — A time domain reflectometer (TDR) is an electronic instrument used to characterize and locate faults in metallic cables (for example, twisted wire pairs, coaxial cables). The equivalent device for optical fiber is an optical time domain… … Wikipedia
Pulse-width modulation — (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey information over a communications channel or control the amount of power sent to a load. PrinciplePulse width modulation uses a square wave whose pulse… … Wikipedia
Pulse-Doppler radar — Pulse Doppler is a radar system capable of not only detecting target location (bearing, range, and altitude), but also measuring its radial velocity (range rate). It uses the Doppler effect to determine the relative velocity of objects; pulses of … Wikipedia
Time of flight diffraction ultrasonics — Time of Flight Diffraction (TOFD) method of Ultrasonic inspection is a very sensitive and accurate method for nondestructive testing of welds for defects. TOFD is a computerised system that was invented in the UK in the 1970s for the nuclear… … Wikipedia
Time-of-flight mass spectrometry — (TOFMS) is a method of mass spectrometry in which ions are accelerated by an electric field of known strength. [Stephens, W. E., [http://link.aps.org/abstract/PR/v69/p674/s2 A Pulsed Mass Spectrometer with Time Dispersion] Phys. Rev. , 1946, 69 … Wikipedia
Time — This article is about the measurement. For the magazine, see Time (magazine). For other uses, see Time (disambiguation). The flow of sand in an hourglass can be used to keep track of elapsed time. It also concretely represents the present as… … Wikipedia
Time-resolved spectroscopy — In physics and physical chemistry, time resolved spectroscopy is the study of dynamic processes in materials or chemical compounds by means of spectroscopic techniques. Most often, processes are studied that occur after illumination of a material … Wikipedia
Pulse forming network — A Pulse Forming Network (PFN) accumulates electrical energy over a comparatively long time, then releases the stored energy in the form of a relatively square pulse of comparatively short duration for various pulsed power applications. In… … Wikipedia
Time in physics — In physics, the treatment of time is a central issue. It has been treated as a question of geometry. One can measure time and treat it as a geometrical dimension, such as length, and perform mathematical operations on it. It is a scalar quantity… … Wikipedia
Time-of-flight — The time of flight (TOF) describes the method used to measure the time that it takes for a particle, object or stream to reach a detector while traveling over a known distance. In time of flight mass spectrometry, ions are accelerated by an… … Wikipedia
