Radio frequency engineering is a subset of electrical engineering that deals with devices that are designed to operate in the radio frequency (RF) spectrum.

On the other side of the frequency spectrum are low frequency vibrations, often not detected by hearing organs, but with other, less specialized sense organs.

Primary properties of visible light are intensity, propagation direction, frequency or wavelength spectrum, and polarisation, while its speed in a vacuum, 299,792,458 meters per second, is one of the fundamental constants of nature.

Plasma frequency The electron plasma frequency (measuring plasma oscillations of the electrons) is large compared to the electron neutral collision frequency (measuring frequency of collisions between electrons and neutral particles).

It might not be what you want to listen to at home, but it works great in the car has a huge frequency spectrum, you know, big bass and high end and the voice kind of stuck in the middle.

The Schumann resonance is a set of spectrum peaks in the ELF portion of the Earth's electromagnetic field spectrum.

A slower processor, with regard to clock frequency, can perform as well as a processor operating at a higher frequency.

The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye.

The Philippine tarsier, has a high frequency limit of auditory sensitivity of approximately 91 kHz with a dominant frequency of 70 kHz.

The original black and white standard, with its 15750 Hz line frequency and 4.5 MHz audio subcarrier, does not meet these requirements, so designers had either to raise the audio subcarrier frequency or lower the line frequency.

Cognitive radio technology, also known as smart radio allowing different radio technologies to share the same spectrum efficiently by adaptively finding unused spectrum and adapting the transmission scheme to the requirements of the technologies currently sharing the spectrum.

Could make some sort of landmark points along a spectrum of improbability, which might look like the electromagnetic spectrum we just looked at.

For example, in the US D, E, and F PCS spectrum blocks, the amount of spectrum available is 5 MHz in each direction.

It didn't occur to me you'd increase your frequency.

The entire Israeli political spectrum was thrown into confusion.

LC circuits are used either for generating signals at a particular frequency, or picking out a signal at a particular frequency from a more complex signal.

Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti sapphire laser.

All blue whale groups make calls at a fundamental frequency between 10 and 40 Hz the lowest frequency sound a human can typically perceive is 20 Hz.

With the end of frequency scaling, these additional transistors (which are no longer used for frequency scaling) can be used to add extra hardware for parallel computing.

The tweet frequency for letter4u from May 8th to 11th.

The frequency and quality of the reporting has also improved.

The threshold frequency, , is the frequency of a photon whose energy is equal to the work function formula_3If is greater than , the energy is enough to remove an electron.

Hurricanes are measured according to three dimensions frequency, intensity, and duration.

Hurricanes are measured according to three dimensions frequency, intensity, and duration.

The frequency of hurricanes has not changed much, if at all.

The frequency is usually in the range 1 to 10 kHz.

Most societies lie somewhere along a spectrum between these two poles.

Full Spectrum Reactions Reactions to the new law have been mixed.

She has been a member of Spectrum Concerts Berlin since 1998.

Our diverse countries suffer a wide spectrum of problems and obstacles.

Radio frequency (RF) is a rate of oscillation in the range of around to , which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.

A hydrogen maser, also known as hydrogen frequency standard, is a specific type of maser that uses the intrinsic properties of the hydrogen atom to serve as a precision frequency reference.

(b) Terms of reference of the mechanism and frequency of its meetings

Increases in frequency increase the amount of power used in a processor.

Little wonder that academics across the political spectrum have expressed considerable skepticism.

The vast center of the Israeli political spectrum nowadays is essentially Herzlian.

Lowering the line frequency is comparatively innocuous, because the horizontal and vertical synchronization information in the NTSC signal allows a receiver to tolerate a substantial amount of variation in the line frequency.

To remove these undesirable frequencies and leave the original signal, the demodulator passes the signal through analog filters that suppress energy outside the expected frequency range (greater than the Nyquist frequency formula_1).

Variations with temperature in the resonance frequency (and other features of the frequency function) are directly related to variations in the Young's modulus, which is a measure of stiffness of the material.

There is a spectrum between mediocre work and good work, and as anybody who's worked as an artist or a creator knows, it's a spectrum you're constantly struggling to get on top of.

America s global military power is undisputed, although it is used with decreasing frequency.

This carrier wave is usually a much higher frequency than the input signal.

Consequently, mechanical wavelengths are much shorter than electrical wavelengths for the same frequency.
