An amplifier which is meant to operate on the linear portion of its characteristic curve(between cutoff and saturation). Thus every instantaneous value of the output is controlled by the input. Theoretically this eliminates all distortion and self-oscillations.  2, fiche 1, Anglais, - linear%20amplifier

Linear amplifiers are used as DC amplifiers, audio amplifiers, measuring instrument amplifiers, radio-frequency amplifiers in single-sideband transmitters, etc. They are also used in analogue computers.  2, fiche 1, Anglais, - linear%20amplifier

Amplificateur qui fonctionne sur la partie linéaire de sa pente caractéristique (entre les points de coupure et de saturation). Ainsi chaque valeur instantanée de la sortie correspond précisément à une valeur particulière du signal d'entrée, ce qui a pour effet d'éliminer, idéalement, toute distorsion et toute oscillation autonome.  2, fiche 1, Français, - amplificateur%20lin%C3%A9aire

Les amplificateurs linéaires servent souvent comme amplificateurs pour courant continu, comme amplificateurs dans les appareils de mesure, comme amplificateurs radiofréquences dans les émetteurs à bande latérale unique, etc. On les utilise également dans les ordinateurs analogiques.  2, fiche 1, Français, - amplificateur%20lin%C3%A9aire

A procedure used to reduce the field of view of a [flame] detector by means of an opaque plate or card with a selected sized opening. This is frequently required to reduce refractory interference to acceptable levels.  2, fiche 2, Anglais, - orificing

The S512 with its PbS photo detector has a linear response from low to medium brightness flames, that is, no distortion of flame signal occurs with regard to any amplifier saturation or AGC action(compression). However, saturation will occur with the PbS element on bright flame. This condition can easily be rectified by using orificing(placing disk with small aperture in front of lens to reduce the amount of light or radiation).  3, fiche 2, Anglais, - orificing

The S512 with its PbS [lead sulfide] photo detector has a linear response from low to medium brightness flames, that is, no distortion of flame signal occurs with regard to any amplifier saturation or AGC action(compression), However, saturation will occur with the PbS element on bright flame. This condition can easily be rectified by using orificing(placing disk with small aperture in front of lens to reduce the amount of light or radiation).  4, fiche 3, Anglais, - amplifier%20saturation

Le convertisseur à résistance négative, étudié en préliminaire, est utilisé pour compenser les pertes d'un circuit LC, en particulier celles de l'inductance. On enregistre alors la «naissance» de l'oscillation qui permet de mettre en évidence la partie à croissance exponentielle et la stabilisation de l'amplitude due à la saturation de l'amplificateur.  2, fiche 3, Français, - saturation%20de%20l%27amplificateur
