43Interaural time difference — The interaural time difference (or ITD) when concerning humans or animals, is the difference in arrival time of a sound between two ears. It is important in the localisation of sounds, as it provides a cue to the direction or angle of the sound… …
44Transformer types — Circuit symbols Transformer with two windings and iron core. Step down or step up transformer. The symbol shows which winding has more turns, but not usually the …
45TOPOGRAPHIE — Étymologiquement, la topographie (du grec 精礼神礼﨟, «lieu») consiste à représenter graphiquement un lieu sur le papier; l’opération correspondante est le levé topographique et le support en est la minute de levé. Deux cas sont à envisager. Dans le… …
46RL circuit — A resistor inductor circuit (RL circuit), or RL filter or RL network, is one of the simplest analogue infinite impulse response electronic filters. It consists of a resistor and an inductor, either in series or in parallel, driven by a voltage… …
47Interferometric synthetic aperture radar — Interferometric synthetic aperture radar, also abbreviated InSAR or IfSAR, is a radar technique used in geodesy and remote sensing. This geodetic method uses two or more synthetic aperture radar (SAR) images to generate maps of surface… …

49Rings of Uranus — The scheme of Uranus s ring moon system. Solid lines denote rings; dashed lines denote orbits of moons. The planet Uranus has a system of rings intermediate in complexity between the more extensive set around Saturn and the simpler systems around …
50Inverse synthetic aperture radar — (ISAR) is a technique to generate a two dimensional high resolution image of a target.In situations where other radars display only a single unidentifiable bright moving pixel, the ISAR image is often adequate to discriminate between various… …
