pulse transmission
41Data transmission — Data transmission, digital transmission, or digital communications is the physical transfer of data (a digital bit stream) over a point to point or point to multipoint communication channel. Examples of such channels are copper wires, optical… …
42Femtosecond pulse shaping — In optics, Femtosecond pulse shaping refers to various techniques to modify the temporal profile of an ultrashort pulse from a laser. Pulse shaping can be used to shorten/elongate the duration of optical pulse, or to generate more complex… …
43Chirped pulse amplification — Diagramatic scheme of chirped pulse amplification. Chirped pulse amplification (CPA) is a technique for amplifying an ultrashort laser pulse up to the petawatt level with the laser pulse being stretched out temporally and spectrally prior to… …
44Microwave transmission — The atmospheric attenuation of microwaves in dry air with a precipitable water vapor level of 0.001 mm. The downward spikes in the graph correspond to frequencies at which microwaves are absorbed more strongly, such as by oxygen molecules… …
45Acoustic transmission lines — An acoustic transmission line is the acoustic analog of the electrical transmission line, typically thought of as a rigid walled tube that is long and thin relative to the wavelength of sound present in it. Pipe organs, woodwinds, and the like… …
46Adaptive Differential Pulse Code Modulation — L’Adaptive Differential Pulse Code Modulation (ADPCM) (en français, Modulation par impulsions et codage différentiel adaptatif (MICDA)) est un algorithme non standardisé de compression de données avec perte. L’algorithme repose sur la présence… …
47Ford 4F27E transmission — 4F27E Manufacturer Ford Motor Company Also called FN4A EL Production 2000 present Predecessor CD4E F 4EAT ATX Class …
48History of radar — The history of radar starts with experiments by Heinrich Hertz in the late 19th century that showed that radio waves were reflected by metallic objects. This possibility was suggested in James Clerk Maxwell s seminal work on electromagnetism.… …
49Action potential — In physiology, an action potential is a short lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, called… …
50Passive radar — systems (also referred to as passive coherent location and passive covert radar) encompass a class of radar systems that detect and track objects by processing reflections from non cooperative sources of illumination in the environment, such as… …
