add example. pulse wave: [ wāv ] 1. a uniformly advancing disturbance in which the parts undergo a change in direction, such as a progressing disturbance on the surface of a liquid. Pulse duration does not change with depth, thus it cannot be changed by the sonographer. Spatial pulse length. Therefore, that information is unavailable for most Encyclopedia.com content. Units of spatial pulse length. The WSR-88D incorporates a variable pulse length that may be as short as 1.57 microseconds (1,545 feet). The pulse interval, or the time from the beginning of one pulse to the beginning of the next, is determined by the number of pulses which are transmitted in a given period of time. Interpretation Translation pulse length. The spatial width of a pulse in the propagation direction is given by the group velocity times the temporal pulse width. A: A 1.0 µ s (1,000 ns) pulse width will test up to 40 km of Corning SMF-28e fiber @1310 nm and 50 km @ … The typical injector pulse width for an idling engine at normal operating temperature is between 2.5 and 3.5 ms. 2) Pulse Length. units of distance, mm, meters. Pulse length Definition from Science & Technology Dictionaries & Glossaries. Returns the length of the pulse in microseconds or gives up and returns 0 if no complete pulse was received within the timeout. The thermal relaxation time of the human hair varies between 10 ms and 100 ms. To achieve the best possible hair removal results, the pulse length should be: a) Less than 10 ms. b) More than 10 ms, but less than 100 ms. c) Longer than 100 ms. d) Pulse length does not matter. In this case, the pulse width (and corresponding duty cycle) change so that the average voltage looks more like an analog output that is not in a steady state such as shown in Figure 1. Despite the high velocity of light, ultrashort pulses can also be very short in the spatial domain. When you feel your pulse, count the number of beats in 15 seconds. (abbr. Can spatial pulse length be changed by the sonographer? durée du plateau de courant. Pulse surveys are different from engagement surveys, lifecycle surveys (onboarding, exit, candidate reaction, etc. If you are visiting our non-English version and want to see the English version of Pulse Length Discrimination, please scroll down to the bottom and you will see the meaning of Pulse Length Discrimination in English language. Pulse length is usually expressed in microseconds, but is also measured in kilometers. The length of time that a pulse is in a given state (high/low) is the “width” of a pulse wave. Both the source and the medium. Returns the length of the pulse in microseconds or gives up and returns 0 if no complete pulse was received within the timeout. The typical injector pulse width for an idling engine at normal operating temperature is between 2.5 and 3.5 ms. Translation of Pulse length in English. The term is used within a number of … the length or distance that a pulse occupies in space from the start to the end of one pulse. The pulse length is a measurement of how long the pulse is. Q: What is the maximum fiber length and pulse width that can be tested with the 150 meter fiber ring? However, the term pulse length is sometimes used in place of pulse duration. The pulse repetition frequency (PRF) is the number of pulses of a repeating signal in a specific time unit, normally measured in pulses per second. The length of the launch and receive cables depends on the link being tested—generally between 300 m and 500 m for multimode testing and between 1000 m and 2000 m for single-mode testing. Pulse length is usually expressed in microseconds, but is also measured in kilometers. Duty cycle − Ratio of the pulse width to the period. Speculators add to CCA length as emitters cut into holdings for sixth straight week. To publish on Pulse, choose a message and start writing. Also known as a pulse width or pulse duration. Most radars automatically adjust the pulse length according to the selected range. What does PLD mean? flat to pulse length in French translation and definition "flat to pulse length", English-French Dictionary online. Units of spatial pulse length. 2. Pulsed operation of lasers refers to any laser not classified as continuous wave, so that the optical power appears in pulses of some duration at some repetition rate.
