Hi,

"Système d'analyse selon..dans lequel un signal impulsionnel généré par le moyen de détection est rejeté par le bloc de traitement de signal correspondant si sa duréée ne dépasse pas une valeur seuil fonction de la vitesse des particules solides dans le milieu"

please help
thank you

impuls(ive) signals When I worked on sonar systems, signals were frequently "impulsive" in nature, which is what we called them (see http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4852... for example). You could say that the (subtle) distiction between an "impulse" signal and an "impulsive" signal is that the former consists entirely of clearly defined rectangular pulses, whereas the latter may also contain analogue components and/or less well defined "pulses". Take your pick, but I would still choose "impulsive"
Zareh Darakjian Ph.D. May 6, 2011:
impulse signal "impulse signal" is the expression used for this type of signal. The signal alternates between peak and trough positions. I don't think that "Impulsive signal" is commonly used.
DLyons May 6, 2011:
@Chris You could well be right, and I see nothing wrong with "impulsive signal" either. Why not post that?
chris collister May 6, 2011:
In this particular case I don't agree that the "signal" part is redundant. We can assume that the frequency and/or duration of each impulse (of which there may be many) is a function of the concentration and/or distribution of particles. The key feature of a "signal" is that it convey information, which a mere pulse might not. I see nothing wrong with "impulsive signal".

pulsed signal

http://www.wipo.int/pctdb/en/wo.jsp?WO=2010040740
System for generating a pulsed signal of the ultra wideband type, comprising a device for direct digital frequency synthesis (DDS) comprising a phase accumulator (ACCP) able to deliver at a first frequency (Fclk) phases coded on i bits and spaced apart by a phase increment (Δp) differing by a power of two and situated in the vicinity of 2i-1, processing means (MT) able to receive said phases and arranged so as to deliver an amplitude-modulated output signal (SG) whose envelope exhibits a succession of regions respectively delimited by zones of zero amplitude (ZA, ZB), each amplitude-modulated signal part situated in one of said regions forming a pulse of the ultra wideband type (IMP) whose central frequency is equal to said first frequency and whose width depends on the value of the phase increment, and control means (MC) able to regulate the operation of the digital synthesis device so as to selectively deliver one or more pulses of the ultra wideband type.
(FR) Système de génération d'un signal impulsionnel du type à bande ultra large, comprenant un dispositif de synthèse numérique directe de fréquence (DDS) comportant un accumulateur de phase (ACCP) apte à délivrer à une première fréquence (Fclk) des phases codées sur i bits mutuellement espacées d'un incrément de phase (Δp) différent d'une puissance de deux et situé au voisinage de 2i-1, et des moyens de traitement (MT) aptes à recevoir lesdites phases et agencés pour délivrer un signal de sortie (SG) modulé en amplitude dont l' enveloppe présente une succession de régions respectivement délimitées par des zones d' amplitude nulle (ZA, ZB), chaque partie de signal modulé en amplitude située dans une desdites régions formant une impulsion du type à bande ultra large (IMP) dont la fréquence centrale est égale à ladite première fréquence et dont la largeur dépend de la valeur de l'incrément de phase, et des moyens de commande (MC) aptes à contrôler le fonctionnement du dispositif de synthèse numérique pour délivrer sélectivement une ou plusieurs impulsions du type à bande ultra large.

"signal" is redundant
