A radar system in which the transmitted signal is linearly frequency-modulated or otherwise spread out in time to reduce the peak power that must be handled by the transmitter; signal amplitude is kept constant; the receiver uses a linear filter to compress the signal and thereby reconstitute a short pulse for the radar display. 2, record 1, English, - pulse%2Dcompression%20radar

Noise Suppression Filter. The patent describes a simple and inexpensive device for filtering undesirable high frequency noise from analog data outputs of a data processing system, which operates in two different modes and switches automatically from one to the other depending on the rate of change of data functions and on data transient amplitude with respect to full scale. 1, record 2, English, - noise%20suppression%20filter

The syllabic filter acts as a low-pass filter for the output signal from the overload algorithm... The slope-voltage output of the syllabic filter is the modulating input to the PAM [Pulse Amplitude Modulator]. The step-function response of the syllabic filter is related to the syllabic rate of speech, is independent of the sampling rate, and is exponential in nature. When the overload algorithm output is true, a charging curve is applicable. When this output is false, a discharging curve is applicable. 2, record 3, English, - syllabic%20filter

Determination of the effective opening size, dw, FIH. The effective opening size of a geotextile, dw, is determined by wet sieving quartz sand of known composition using modified sieving equipment. The geotextile functions as a sieve.... The test sample,(diameter 18 cm), is clamped into a sieve frame. The sand, which has a dry weight of 100 g for wovens and a dry weight of 300 g for non-wovens, is then sprinkled onto the sample. The sand is then sprayed continuously with water and sieved for 15 minutes in a modified sieve machine with a vertical amplitude of 3 mm at a frequency of 50 Hz. The sand which passes through the geotextile sample is caught on a paper filter and then analyzed with [different sieves].... The effective opening size, dw, is found from the coarsest sand fraction which has passed through the test sample and in which there is still a defined quantity in relation to the original fraction. 4, record 4, English, - effective%20opening%20size

The third technique for determining the pore size distribution is based upon wet sieving. Again, there are several variations on the basic concept .... The FIH (Franzius Institut Hanover] method determines a parameter known as the "Wet Sieving Effective opening Size" (Dw), which is sometimes considered approximately equivalent to the 90% opening size .... However, as test results obtained by Heerten demonstrate this relationship is neither accurate nor consistent. 3, record 4, English, - effective%20opening%20size

Sur les échantillons géotextiles ont été réalisés: - des essais de traction, - des mesures d'ouverture de filtration [...] Les essais ont montré que les géotextiles avaient conservé leurs propriétés mécaniques (résistance en traction) et hydrauliques (permittivité et ouverture de filtration sur échantillons lavés). Autrement dit, après 20 ans en service, les caractéristiques, utilisées pour les critères de dimensionnement du filtre, restent inchangées. 2, record 4, French, - ouverture%20de%20filtration%20effective

A filter used before sampling to remove undesired frequencies which the sampling process would otherwise alias. An alias filter should have linear phase response and nearly flat amplitude response over the signal passband and should roll off rapidly above this band to provide high attenuation above the Nyquist frequency(.,..)

Afin d'éviter ces phénomènes, il est donc nécessaire de filtrer l'enregistrement avant l'échantillonnage afin de l'épurer de toutes les fréquences supérieures à la fréquence de Nyquist. On utilise à cet effet un filtre à pente raide, dit filtre antialiasing, dont la fréquence est naturellement adaptée à l'échantillonnage. 1, record 5, French, - filtre%20antialiasing
