In radar, measurement of pulse transmission time in microseconds; that is, the time the radar's transmitter is energized during each cycle. In optics, an ultrashort pulse of light is an electromagnetic pulse whose time duration is of the order of a picosecond (10 −12 second) or less. The shorter the pulse duration, the better the axial resolution. It is the ‘work’ part of the spark cycle, when the current flows and work is done only during this time. Learn definitions, uses, and phrases with pulse-duration. Definition: Laser is a type of electronic device that is built based on the quantum principle which creates a beam of single color photons with the same frequency and phase. The average value of voltage (and current) fed to the load is controlled by turning the switch between supply and load on and off at a fast rate. Which pulse is likely to create best image? pulse duration: 1. The pulses have different durations. means a time in-terval, expressed in seconds, beginning at the first time the pressure ampli- tude exceeds the minimum pressure amplitude plus 10 percent of the dif- ference between the maximum and minimum pressure amplitudes, and ending at the last time the pressure amplitude returns to this value. There are actually different definitions of a pulse duration: The most frequently used definition is based on the full width at half-maximum (FWHM) of the optical power versus time. VF−TLP systems are primarily used to explore charged device model (CDM) behavior in integrated circuits. Origin. Haruhisa SAKAMOTO * and Koji MORIOKA ** * Sophia University, Faculty of Science Technology , 7-1 Kioi-cho, Chiyoda-ku, Tokyo 102-8554, Japan . It's here! Pulse width modulation (PWM), or pulse-duration modulation (PDM), is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts. Another kind of pulse modulation is pulse-duration modulation (PDM), in which intelligence is represented by the length and order of regularly recurring pulses. Pulse definition is - the regular expansion of an artery caused by the ejection of blood into the arterial system by the contractions of the heart. Definition: a limit for the time–bandwidth–product of an optical pulse. Definition of pulse duration modulation in English: pulse duration modulation. What is the meaning of pulse duration modulation? Report an issue with this definition: source: FAA Flight Navigator's Handbook (FAA-H-8083-18) The time over which a radar pulse lasts. Word of the day. Increasing the duration of a transmitted pulse increases its energy and improves target detection capability. Pulse duration In signal processing and telecommunication, the term pulse duration has the following meanings: Pulse duration using 50% peak amplitude. Pulse duration is the period of time the current is allowed to flow per cycle during the micro-EDM process. Words for Places. Definition of the Pulse Duration. In practical electronic and computer systems, a pulse may last from a fraction of a nanosecond up to several seconds or even minutes. I have a laser with a short pulse duration (sub 20 fs) and i want to know how long the pulse would be after it passes through X amount of material. In a pulse waveform, the interval between (a) the time, during the first transition, that the pulse amplitude reaches a specified fraction (level) of its final amplitude, and (b) the time the pulse amplitude drops, on the last transition, to the same level. Terms and Definitions. What are synonyms for pulse duration … Examples. They are commonly referred to as ultrafast events. These terms are often confused or used interchangeably, when they are actually three different ways of measuring an electrical signal. A familiar example of PDM is the International Morse Code, used in ship-to-shore communications, amateur radio, and certain other forms of radiotelegraphy. pulse duration. pulse duration: (in ultrasonics) a measure of the time a transducer oscillates for each pulse.

Match all exact any words “Pulse duration” equal to or exceeding 1 ps and less than 1 ns and any of the following: EurLex-2 EurLex-2. definition - Pulse duration. Since the width is changing, the power loss can be reduced when compared to PAM signals. Stem. The terms "short pulse" and "ultrashort pulse" are a bit general--typically 200 picoseconds down to femtosecond level durations--but when the pulse length becomes this short, material removal becomes a function of vaporization or sublimation rather than absorption. rms pulse duration.
