Abstract

Abstract Translated from French Dispositif de détermination de l'instant d'arrivée d'une impulsion, à front de montée rapide ou lent. Comprend un premier comparateur (1) auquel sont appliquées respectivement à ses entrées une impulsion retardée (C1) et une impulsion atténuée (F1) non retardée, et un second comparateur (9) en parallèle sur le premier, par l'intermédiaire d'un circuit logique ET (14) recevant l'impulsion appliquée à l'entrée (E) du dispositif à travers un circuit (10) connnectée à une de ses entrées, agissant sur le bruit et/ou le signal. Ce circuit (10) est soit un filtre passe-bas, soit un circuit diviseur. Application aux équipements de mesure de distances (DME). Device for determining the moment of arrival of a pulse, with a fast or slow rising edge. Includes a first comparator (1) to which are applied respectively to its inputs a delayed pulse (C1) and an attenuated pulse (F1), and a second comparator (9) in parallel on the first, via a AND logic circuit (14) receiving the pulse applied to the input (E) of the device through a circuit (10) connected to one of its inputs, acting on the noise and / or the signal. This circuit (10) is either a low-pass filter or a divider circuit. Application to distance measuring equipment (DME).
