This technique causes the system to respond only to low frequency acceleration components such as the platform tilt.

The effect is that the platform returns from an off-level position at a rapid rate until it is nearly level, at which point the platform is controlled by a proportional servo with low enough frequency response so that the noise has little effect on the leveling process.

Only high frequency sounds like mating calls are heard in this way but low frequency noises can be detected through another mechanism.

MtDNA Haplogroup D is found frequently throughout East Asia and Central Asia, and is also common in some populations of North Asia, Southeast Asia, and the Americas ; in addition, it has been found with low frequency in some populations of Europe and Southwest Asia.

Modern switching amplifiers need steep low pass filtering at the output to get rid of high frequency switching noise and harmonics.

Bass ( ) describes tones of low frequency or range.

This is barely noticeable at low frequencies but is quite evident at frequencies close to the Nyquist frequency.

They postulated that extremely low frequency ( ELF ) propagation might be involved, since Faraday cage screening is less effective in the ELF range.

Mahogany raises the frequency of low pitches and keeps higher frequencies at about the same speed.

The DTMF keypad is laid out in a 4 × 4 matrix, with each row representing a low frequency, and each column representing a high frequency.

An unamplified acoustic bass's tone is limited by the frequency responsiveness of the instrument's hollow body, which means that the very low pitches may not be as loud as the higher pitches.

With an amplifier and equalization devices, a bass player can boost the low frequencies, which evens out the frequency response.

The Decca Navigator System was a low frequency radio navigation system which allowed ships and aircraft to determine their position by receiving radio signals from fixed navigational beacons with a receiving unit.

Legend: γ = Gamma ray s HX = Hard X-ray s SX = Soft X-Rays EUV = Extreme-ultraviolet NUV = Near-ultraviolet Visible light ( colored bands ) NIR = Near-infrared MIR = Moderate-infrared FIR = Far-infrared EHF = Extremely high frequency ( microwaves ) SHF = Super-high frequency ( microwaves ) UHF = Ultrahigh frequency ( radio waves ) VHF = Very high frequency ( radio ) HF = High frequency ( radio ) MF = Medium frequency ( radio ) LF = Low frequency ( radio ) VLF = Very low frequency ( radio ) VF = Voice frequency ULF = Ultra-low frequency ( radio ) SLF = Super-low frequency ( radio ) ELF = Extremely low frequency ( radio )

The Ca < sup > 2 +</ sup > is bound with low affinity, but high capacity, and can be released on a signal ( see inositol triphosphate ).

Inefficiency comes not just from the fact that the device is always conducting to some extent ( that happens even with class AB, yet its efficiency can be close to that of class B ); it is that the standing current is roughly half the maximum output current ( although this can be less with square law output stage ), together with the problem that a large part of the power supply voltage is developed across the output device at low signal levels ( as with classes AB and B, but unlike output stages such as class D ).

Typically the Quadravalve / PD-05 signal makes up the low end while a balance of the U5 and RBI make up the high end, with the RBI providing the " top end " distortion in Lee's sound.

Hall effect devices produce a very low signal level and thus require amplification.

In practice, 802. 11b typically has a higher range at low speeds ( 802. 11b will reduce speed to 5 Mbit / s or even 1 Mbit / s at low signal strengths ).

The lowball signal was indicated when the weighted ball, and therefore signal, was at the end of its rope in the low position, indicating stop.

LEDs used outdoors, such as traffic signals or in-pavement signal lights, and that are utilized in climates where the temperature within the luminaire gets very hot, could result in low signal intensities or even failure.

Any of these properties can be modified in accordance with a low frequency signal to obtain the modulated signal.

# Map the codewords to attributes, for example amplitudes of the I and Q signals ( the equivalent low pass signal ), or frequency or phase values.

# Adapt pulse shaping or some other filtering to limit the bandwidth and form the spectrum of the equivalent low pass signal, typically using digital signal processing.

Carry out the modulation, for example by multiplying the sine and cosine waveform with the I and Q signals, resulting in the equivalent low pass signal being frequency shifted to the modulated passband signal or RF signal.

In some cases, serial data is not exchanged, but the control lines are used to signal conditions such as loss of power or low battery alarms.

Additionally, coating may increase signal / noise ratio for samples of low atomic number ( Z ).

Due to the limited size of the SNO detector in comparison with Super-K the low cosmic ray neutrino signal is not statistically significant at neutrino energies below 1 GeV.

To conserve bandwidth, SSB would be desirable, but the video signal has significant low frequency content ( average brightness ) and has rectangular synchronising pulses.

AM demodulation requires the simple rectification of the RF signal ( so-called envelope detection ), and a simple RC low pass filter to remove remnants of the intermediate frequency.

Magnetic tape has a nonlinear response at low signal strengths, as measured by its coercivity.

For small power and signal transformers, in which currents are low and the potential difference between adjacent turns is small, the coils are often wound from enamelled magnet wire, such as Formvar wire.

in the cold dawn the mist swirled low to the ground, then rose with a gust of sudden wind to leave the valley clear.

As she was rather tired this evening, her simple `` Thank you for the use of your bath '' -- when she sat down opposite him -- spoken in a low voice, came across with coolnesses of intelligence and control.

Such characters, with their low existence and often low morality, produce humorous effects in his novels and tales, as they did in the writing of Longstreet and Hooper and Harris, but it need not be added that he gives them far subtler and more intricate functions than they had in the earlier writers ; ;

Master Gorton, having foully abused high and low at Aquidneck is now bewitching and bemaddening poor Providence, both with his unclean and foul censures of all the ministers of this country ( for which myself have in Christ's name withstood him ), and also denying all visible and external ordinances in depth of Familism: almost all suck in his poison, as at first they did at Aquidneck.

But during the second half of the century its fortunes reached a low point and when in 1897 Cyrus H. K. Curtis purchased it -- `` paper, type, and all '' -- for $1,000 it was a 16-page weekly filled with unsigned fiction and initialed miscellany, and with only some 2,000 subscribers.

But it had, as was usual in southern cities of this sort, a Black Bottom, a low region near the river where the Negroes lived -- servants and laborers huddled together in a region with no sewage save the river, where streets and sidewalks were neglected and where there was much poverty and crime.

A tall lady, with a ruffled collar very low on her bosom, turned insolent green eyes upon him.

Beyond that misty gray of the rain, he saw the stretching hutment, low diminutive log cabins, chinked with mud, with doorways a man would have to crouch to get through, with roofs of tenting laid over boughs or boards from hardtack boxes, or fence rails, with cranky chimneys of sticks and dried mud.

Looking around slowly, he saw a marble fireplace, a desk, a low bookcase of mahogany with criss-crossed brass wire instead of glass panes in the doors.

These provisions are designed to reflect the differences in wealth and population among the States, with the objective that a vocationally handicapped person have access to needed services regardless of whether he resides in a State with a low or high per capita income or a sparsely or thickly populated State.

The Peace Corps can either begin in very low gear, with only preparatory work undertaken between now and when Congress finally appropriates special funds for it -- or it can be launched now and in earnest by executive action, with sufficient funds and made available from existing Mutual Security appropriations to permit a number of substantial projects to start this summer.

Taking the path behind the Throne Room to the building directly beyond it, the Portrait Gallery, I went right at the end of it, through a garden to a small building at the back -- a sitting room furnished with low blue divans, its floor covered with carpets, its ceiling painted with gold squares and floral designs.

The results of present observations of the thermal radio emission of the moon are consistent with the very low thermal conductivity of the surface layer which was derived from the variation in the infrared emission during eclipses ( e.g., Garstung, 1958 ).

The low intensity of the radiation from Saturn has limited observations, but again the measured radiation seems to be consistent with a thermal origin.

Argon was also blown at low velocities ( mass flow rate Af ) through a tube coaxial with the cathode as an additional precaution against contamination of the arc by air.

Mason and Taylor both show that the major axis of the ellipsoids is at 45-degrees at low rates of shear and that it approaches the direction of shear with increased rates of shear.
