This noise can be avoided by modulation of the signal at a higher frequency, for example through the use of a lock-in amplifier.

For example, a 3 kHz band can carry a telephone conversation whether that band is at baseband ( as in your POTS telephone line ) or modulated to some higher frequency.

Metro rail or rapid transit usually covers a smaller inner-urban area ranging outwards to between 12 km to 20 km ( or 8 to 14 miles ), has a higher train frequency and runs on separate tracks ( underground or elevated ), whereas commuter rail often shares tracks, technology and the legal framework with mainline railway.

When the tension is increased, the amplitude of the sound is reduced and the frequency is increased, making the pitch higher and the volume lower.

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

The waves " bunch together ", so the time between arrival of successive wavefront s is reduced, giving them a higher frequency.

The received frequency is higher ( compared to the emitted frequency ) during the approach, it is identical at the instant of passing by, and it is lower during the recession.

He confirmed that the sound's pitch was higher than the emitted frequency when the sound source approached him, and lower than the emitted frequency when the sound source receded from him.

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.

Because this band is higher in frequency than bands currently in use by deep-space missions, the same amount of data can be sent by smaller equipment in space and on the ground.

By contrast, for higher frequency radiations at ultraviolet frequencies and above ( i. e., X-rays and gamma rays ) the damage to chemical materials and living cells by EMR is far larger than that done by simple heating, due to the ability of single photons in such high frequency EMR to damage individual molecules chemically.

In 1910 British physicist William Henry Bragg demonstrated that gamma rays are electromagnetic radiation, not particles, and in 1914 Rutherford and Edward Andrade measured their wavelengths, and found that they were similar to X-rays but with shorter wavelengths and higher frequency.

Most electromagnetic waves of higher frequency than visible light ( UV and X-rays ) are blocked by absorption from electronic excitation in ozone and dioxygen ( for UV ), and by ionization of air for energies in the extreme UV and above.

Class-D amplifiers have been widely used to control motors, and are used almost exclusively for small DC motors, but they are now also used as audio amplifiers, with some extra circuitry to allow analogue to be converted to a much higher frequency pulse width modulated signal.

For the same reason, filter functions whose critical response is at lower frequencies ( compared to the sampling frequency 1 / T ) require a higher order, more computationally intensive FIR filter.

This is as a direct result of Gravitational time dilation ; frequency of the electromagnetic radiation is reduced in an area of a higher gravitational potential.

Frequency modulation can be classified as narrowband if the change in the carrier frequency is about the same as the signal frequency, or as wideband if the change in the carrier frequency is much higher ( modulation index > 1 ) than the signal frequency.

These transistors are capable of a 100 GHz cutoff frequency, much higher than standard silicon FETs.

Examples of FTL proposals are changing the " frequency " of mass to a higher state by applying high-frequency waves of energy, the Alcubierre drive, and the traversable wormhole, although the physical plausibility of some of these solutions is uncertain.

Among them, according to the U.S. Department of Commerce, are: ( 1 ) shorter work weeks, ( 2 ) higher pay, ( 3 ) longer paid vacations, ( 4 ) better transportation, ( 5 ) earlier retirement, and ( 6 ) more education.

This relation, however, is a psychological one in contrast to the physical relation implied by Wien's displacement law, according to which the spectral peak is shifted towards shorter wavelengths ( resulting in a more blueish white ) for higher temperatures.

Lower frequencies have longer wavelengths, and higher frequencies have shorter wavelengths, and are associated with photons of higher energy.

Electromagnetic-type ionizing radiation extends from the extreme ultraviolet to all higher frequencies and shorter wavelengths, which means that all X-rays and gamma rays are ionizing radiation.

LB is relatively new and is ineffective in resolving fragments larger than 5 kbp ; However, with its low conductivity, a much higher voltage could be used ( up to 35 V / cm ), which means a shorter analysis time for routine electrophoresis.

Powder used for rocketry can use a slower burn rate since it will accelerate the projectile for a much longer period of time, whereas powders for use in weapons such as flintlocks, caplocks or matchlocks need a higher burn rate since they must accelerate the projectile in a much shorter distance.

The shorter the time of change in acceleration, such as a rollercoaster ' whipping ' around a corner, the higher the jerk.

Resolution in these microscopes is limited by the wavelength of the radiation used to image the sample, where shorter wavelengths allow for a higher resolution.

Neutrons are capable of producing an even higher degeneracy pressure, albeit over a shorter range.

Generally a shorter half-life leads to a higher time resolution at the expense of timescale.

From 1979 onwards, punk-influenced skinheads with shorter hair, higher boots and less emphasis on traditional styles grew in numbers and grabbed media attention, mostly due to football hooliganism.

skinheads — influenced by the 1970s punk subculture — often have shorter hair than 1960s-style skinheads, and tend to wear higher boots, tighter jeans, and clothing styles that are less mod-influenced than their traditionalist counterparts.

The spot size and the interaction volume are both large compared to the distances between atoms, so the resolution of the SEM is not high enough to image individual atoms, as is possible in the shorter wavelength ( i. e. higher energy ) transmission electron microscope ( TEM ).

In May 1902, United Mine Workers went on strike to get higher pay wages and shorter workdays.

Taylor argues most people " were enjoying a richer life than any previously known in the history of the world: longer holidays, shorter hours, higher real wages.

The wide, wild steps of the country people became shorter and more elegant when introduced to higher society.

Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths.

As with other diffraction patterns, the pattern scales in proportion to wavelength, so shorter wavelengths can lead to higher resolution.

For rugged objects, much higher accelerations may suffice, allowing a far shorter track, potentially circular or helical ( spiral ).

This would provide much higher acceleration than a solar sail driven by a laser, but a charged particle beam would disperse in a shorter distance than a laser due to the electrostatic repulsion of its component particles.

A higher speed and / or a shorter rope makes the task more difficult.

The shorter the interval between the coils, the higher the cut-off frequency.
