The transform preserves stability and maps every point of the frequency response of the continuous-time filter, to a corresponding point in the frequency response of the discrete-time filter, although to a somewhat different frequency, as shown in the Frequency warping section below.

Frequency response is the quantitative measure of the output spectrum of a system or device in response to a stimulus, and is used to characterize the dynamics of the system.

Frequency response of a low pass filter with 6 dB per octave or 20 dB per decade

Frequency response requirements differ depending on the application.

Frequency response curves are often used to indicate the accuracy of electronic components or systems.

; Frequency response ( Fs ): This measurement tells you over what frequency range output level for an audio component will remain reasonably constant ( either within a specified decibel range, or no more than a certain number of dB from the amplitude at 1kHz ).

* Frequency response

Frequency compensation is implemented to optimize step response, one method being pole splitting.

The U. S. treats these nations uniquely by giving them access to many U. S. domestic programs, including disaster response and recovery and hazard mitigation programs under the Federal Emergency Management Agency, and services provided by the National Weather Service, the United States Postal Service, the Federal Aviation Administration, the Federal Communications Commission, and U. S. representation to the International Frequency Registration Board of the International Telecommunications Union.

Frequency response of a high gain amplifier is limited to about one-tenth the excitation frequency, although this is often mitigated by exciting magnetic amplifiers with currents at higher than utility frequency.

* Frequency following response

Frequency response analysis enables simultaneous monitoring of the various processes that contribute to the potentiodynamic ac response of electrochemical system.

: which is of the form suggested the previous year by M. J. Buckingham in Very High Frequency Absorption in Superconductors based on the fact that the superconducting phase transition is second order, that the superconducting phase has a mass gap and on Blevins, Gordy and Fairbank's experimental results the previous year on the absorption of millimeter waves by superconducting tin.

Frequency domain analysis is also called spectrum-or spectral analysis.

Within the IMT-2000 group of technologies, DECT is referred to as IMT-2000 Frequency Time ( IMT-FT )

* Frequency: in Europe, in China, in Japan, in Latin America and in the US and Canada, and products may NOT be used in the UK or Ireland as they cause and suffer from interference with the UK and Ireland cellular networks with illegal use of such products being prohibited by UK agencies, and UK and Ireland DECT and products may NOT be used in the US and Canada as they cause and suffer from interference with US and Canada cellular networks and aircraft and for that reason is deemed illegal to use by US and Canadian agencies such as the Federal Communication Commission and Industry Canada.

Frequency is inversely proportional to wavelength, according to the equation:

Frequency is the number of occurrences of a repeating event per unit time.

Frequency modulation is also used in telemetry, radar, seismic prospecting and newborn EEG seizure monitoring.

Frequency modulation is known as phase modulation when the carrier phase modulation is the time integral of the FM signal.

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.

The first is through VLF ( Very Low Frequency ) radio waves launched into the magnetosphere.

The Pelvic Pain Urgency / Frequency ( PUF ) Patient Survey, created by C. Lowell Parsons, is a short questionnaire that will help physicians identify if pelvic pain could be coming from the bladder.

** Frequency modulation ( FM ) ( here the frequency of the carrier signal is varied in accordance to the instantaneous amplitude of the modulating signal )

Frequency shift is caused by motion that changes the number of wavelengths between the reflector and the radar.

Frequency comparison between two signals is considerably more accurate, even with older electronics, than timing the signal.

Use ( USE ) and Used For ( UF ) indicators are used when an authorized term is to be used for another, unauthorized, term ; for example, the entry for the authorized term " Frequency " could have the indicator " UF Pitch ".

In radio systems, TDMA is usually used alongside Frequency-division multiple access ( FDMA ) and Frequency division duplex ( FDD ); the combination is referred to as FDMA / TDMA / FDD.

The modulation method is 8ary Frequency Shift Keying or 8FSK, also sometimes called Multi Frequency Shift Keying MFSK, with eight orthogonal tones between 750 and 2500 Hz.

The Ham Radio Global ALE High Frequency Network, which began service in June 2007, is the world's largest intentionally open ALE network for internet connectivity.

That said, it is also used in the Radio Frequency ( RF ) regime for cases in which the antenna is operating in the so-called optical region and is likewise very large relative to a wavelength.

* Radio Frequency Interference ( RFI ), from typically 20 kHz to an upper limit which constantly increases as technology pushes it higher.

The region is typically defined by the location of the signal Instantaneous Frequency, as most of the signal energy to be preserved is concentrated about it.

Frequency division ( FD ) bat detectors synthesise a sound which is a fraction of the bat call frequencies, typically 1 / 10.

Frequency display dials may either be analog ( typically marked to fine increments for accuracy ) or digital.

Technologies typically considered as part of AIDC include bar codes, Radio Frequency Identification ( RFID ), biometrics, magnetic stripes, Optical Character Recognition ( OCR ), smart cards, and voice recognition.

Frequency changers are typically used to control the speed of motors, primarily pumps and fans.
