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

Boss Audio class-D mono car audio amplifier with a low pass filter for powering subwoofer s

The low church Whigs had failed in their attempt to pass the Exclusion Bill to exclude James from the throne between 1679 and 1681, and James's supporters were the high church Anglican Tories.

This is necessary as the gas density in the tube is usually low, and most high energy gamma photons pass through undetected.

Analog and digital modulation facilitate frequency division multiplexing ( FDM ), where several low pass information signals are transferred simultaneously over the same shared physical medium, using separate passband channels ( several different carrier frequencies ).

# 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.

Some areas of the world such as Washington and Oregon in the United States, and Wales in the United Kingdom, have used geographic features to store large quantities of water in elevated reservoirs, using excess electricity at times of low demand to pump water up to the reservoirs, then letting the water pass through turbine generators to retrieve the energy when electrical demands peak.

To this end the glass is of a special low iron type that allows 90 % of the ultraviolet light in sunlight to pass.

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.

In telecommunications in particular, it is often the case that those parts of the signal which are at low frequencies are " copied " up to higher frequencies for transmission purposes, since there are few communications media that will pass low frequencies without distortion.

ADM reduces slope error, at the expense of increasing quantizing error. This error can be reduced by using a low pass filter.

The final implementation replaced the integrator with a Predictor implemented with a two pole complex pair low pass filter designed to approximate the long term average speech spectrum.

As such, designing a filter consists of developing specifications appropriate to the problem ( for example, a second-order low pass filter with a specific cut-off frequency ), and then producing a transfer function which meets the specifications.

A digital filter will introduce noise to a signal during analog low pass filtering, analog to digital conversion, digital to analog conversion and may introduce digital noise due to quantization.

Introducing a digital filter requires considerable overhead circuitry, as previously discussed, including two low pass analog filters.

All systems are low pass to some extent.

Early in the match, Arsenal midfielder Robert Pirès played a low pass from the left flank to Bergkamp in the edge of the opponent area with his back to goal.

As the low and the warm front pass, the nimbostratus thins out into low stratus and the precipitation tapers off.

As long as the bar is not so low that it touches the lifter ’ s belt, it is acceptable.

White iron is too brittle for use in many structural components, but with good hardness and abrasion resistance and relatively low cost, it finds use in such applications as the wear surfaces ( impeller and volute ) of slurry pumps, shell liners and lifter bars in ball mills and autogenous grinding mills, balls and rings in coal pulverisers, and the teeth of a backhoe's digging bucket ( although cast medium-carbon martensitic steel is more common for this application ).

Due to the relatively low mass of the valve train, mechanical lifter versions of the " W " engine were capable of operating at speeds well beyond 6000 RPM.

Valves are driven by roller-follower rocker arms with low friction roller bearings, and a unique, concave cam lobe design to increase valve lift over the traditional shimless lifter type system of the 1GR-FE.

The bar is approached with back straight, and the lifter crouches low and grasps the bar, with the balls of the feet directly under it.

Others are confined to vast reservations, and not only does the Australian government justifiably not wish them to be viewed as exhibits in a zoo, but on their reservations they are extremely fugitive, shunning camps, coming together only for corroborees at which their strange culture comes to its highest pitch -- which is very low indeed.

Such a comparison reminds us that in employing low characters in his works Faulkner is recording actuality in the South and moreover is following a long-established literary precedent.

What is more, the legends have become so sacrosanct that the very habit of self-examination or self-criticism smells of low treason, and men who practice it are defeatists and unpatriotic scoundrels.

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.

Milton's name being fourth is neither too high nor too low to be assigned to the arbitrary action of vice-chancellor, proctor, master, or other mighty hand.

The national average is more than $4 and that figure is considered by experts in the mental health field to be too low.

It is low when the thyroid is overactive and high when the gland is sluggish.

What we are attempting to do is achieve and maintain a balance between medium density and low density residential areas and industrial and commercial development.

West Berlin morale is low and, in age distribution, the situation is unfavorable.

Since conventional methods are insensitive at the low frequencies of these molecular transitions, the paramagnetic resonance method is being used instead.

Before it cycles on again, humidity can build up and make you uncomfortable even though the temperature is still low.

A new low capacity meter is the key that unlocks the situation at Oakwood Heights.

The major gets the assured gallonage for the life of the lease and the distributor apparently can do well because delivery cost is low.

The charge is variable, however, and goes as low as $.50 a day in Ireland and as high as $2.00 a day in Greece.

No attempts to measure the radio emission of the remaining planets have been reported, and, because of their distances, small diameters, or low temperatures, the thermal radiation at radio wave lengths reaching the earth from these sources is expected to be of very low intensity.

Essentially these birefringence studies show that at low rates of shear a tension is present at 45-degrees to the direction of shear, and as the rate of shear increases, the direction of the maximum tension moves asymptotically toward the direction of shear.

There is another means which should show the direction and relative value of the stresses in viscoelastic fluids that is not mentioned as such in the literature, and that is the shape of the suspended drops of low viscosity fluids in shear fields.
