Moderate use of equalization ( often abbreviated as " EQ ") can be used to " fine-tune " the tone quality of a recording ; extreme use of equalization, such as heavily cutting a certain frequency can create more unusual effects.

It is a mathematical tool for finding repeating patterns, such as the presence of a periodic signal which has been buried under noise, or identifying the missing fundamental frequency in a signal implied by its harmonic frequencies.

Because such strains transfer chromosomal genes very efficiently they are called Hfr ( high frequency of recombination ).

Wing-beat frequency normally increases as size decreases, but as the bee's wing beat covers such a small arc, it flaps approximately 230 times per second, faster than a fruitfly ( 200 times per second ) which is 80 times smaller.

This overcomes the limitations of classical control theory in more sophisticated design problems, such as fighter aircraft control, with the limitation that no frequency domain analysis is possible.

In algorithms such as MP3, however, a large number of samples have to be analyzed in order to implement a psychoacoustic model in the frequency domain, and latency is on the order of 23 ms ( 46 ms for two-way communication ).

Yamaha's engineers began adapting Chowning's algorithm for use in a commercial digital synthesizer, adding improvements such as the " key scaling " method to avoid the introduction of distortion that normally occurred in analog systems during frequency modulation, though it would take several years before Yamaha release their FM digital synthesizers.

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.

When any wire ( or other conducting object such as an antenna ) conducts alternating current, electromagnetic radiation is propagated at the same frequency as the electric current.

The most common form of linear oscillator is an electronic amplifier such as a transistor or op amp connected in a feedback loop with its output fed back into its input through a frequency selective electronic filter to provide positive feedback.

LC oscillators are often used at radio frequencies, when a tunable frequency source is necessary, such as in signal generators, tunable radio transmitters and the local oscillators in radio receivers.

These amplifiers use pulse width modulation, pulse density modulation ( sometimes referred to as pulse frequency modulation ) or a more advanced form of modulation such as Delta-sigma modulation ( for example, in the Analog Devices AD1990 class-D audio power amplifier ).

The complexity of any such filter is given by the order N, which describes the order of the rational function describing the frequency response.

Scholars such as Goswin König and A. C. Bradley have estimated approximate dates of undated works of Shakespeare by studying the frequency of enjambment.

For cyclical processes, such as rotation, oscillations, or waves, frequency is defined as a number of cycles per unit time.

According to Bordes, the presence or absence of tool types, or differences in the frequency of types between assemblages, were manifestations of cultural differences between ethnic groups.

Accordingly, the Commission has recognized that an optimum allocation pattern for one frequency does not necessarily represent the best pattern for other frequencies, and has assigned different frequencies for use by different classes of stations.

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.

In this, some base signal ( e. g., a sinusoidal carrier wave ) has one of its properties modulated: amplitude modulation involves altering the amplitude of a sinusoidal voltage waveform by the source information, frequency modulation changes the frequency.

Despite the frequency with which this name is used as a polemical label, there has been no historically continuous survival of Arianism into the modern era.

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.

Haplogroup M7a has been found elsewhere mainly among Japanese and Ryukyuans, and with lower frequency among Udegeys, Koreans, Chinese, Filipinos, Taiwanese aborigines, Buryats, Central Asians, and Waars of the Jaintia Hills in Meghalaya, India.

E. g., a passband filter that has a bandwidth of 2 MHz with center frequency 10 MHz will have a fractional bandwidth of 2 / 10, or 20 %.

The age of the patient and the frequency with which BCG is given has always varied from country to country.

The choice of isotope ordinarily has little effect on the electrical properties of a material, but does affect the frequency of lattice vibrations, this effect suggested that superconductivity be related to vibrations of the lattice.

The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 hertz and that has a radiant intensity in that direction of watt per steradian.

Compared to rapid transit ( or metro rail ), commuter / suburban rail has lower frequency, following a schedule rather than fixed intervals, and fewer stations spaced further apart.

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.
