Frequency, английский
- A measure of the rate of occurrence of an event expressed as the number of occurrences of an event in a given time. see also likelihood & probability
- Частота
- The number of times a wave-like radio signal changes from the very positive to the very negative charge per second.
- The number of complete cycles of a periodic waveform that occur in a given length of
- Standard, primary основной эталон частоты
- The number of times a complete electromagnetic wave cycle occurs in a fixed unit of time, usually one second. the rate at which a current alternates, measured in hertz on a telecommunications medium.
- The number of complete cycles of a periodic waveform that occur in a given length of time. usually specified in cycles per second (hertz).
- The number of cycles per unit of time, denoted by hertz (hz); 1 hertz 1 cycle per second
- The number of times that the wave oscillates per second (the number of periods of oscillations per second). also, the number of light waves passing a fixed point in a given unit of time, or the number of complete vibrations in that period of time.
- The number of times an electromagnetic wave oscillates in a second, or the number of wave peaks that pass a point in second; measured in hertz.
- Frecuencia
- The number of oscillations per second (a) of the current or voltage in an alternating- current electric circuit, or (b) of a sound wave, fresco 442 or (c) of a vibrating solid object; expressed in hertz (abbr. hz) or in cycles per second (abbr. cps). fresco, buon fresco the technique of painting water colors on plaster when it is almost but not quite dry; in such work, waterbased colors unite with the base; any retouching is done when the plaster is dry (i.e., fresco secco). fresco secco, secco a mural, often fugitive, painted with water-based colors on dry plaster.
- 1. the number of times something takes place in a given time the frequency of micturition 2. the rate of vibration in oscillations
- Стабильность частоты
- N частота; частотность; повторяемость fundamental ~ основаная частота list ~ частота в списке text ~ текстовая частота
- Частота ~ of concrete vibrator частота колебаний, создаваемых вибратором при уплотнении бетонной смеси ~ of occurrence повторяемость (напр, гидрологической величины) ~ of sampling частота отбора проб
- The number of crests passing a fixed point at a given time.
- The number of repetitions per unit time of a complete waveform, expressed in hertz (hz).
- Measured in hertz (hz), the number of cycles per second of a sound wave or audio signal. a high-frequency sound (example, 12,000 hz) has a high pitch, and a low-frequency sound (example, 200 hz) has a low pitch.
- The number of times a category of events, of objects or of individuals has been observed, the number of members in a class (->probability, ->law of large numbers).
- In windows media player, the number, such as 88.5 or 101.7, used to locate a radio station.
- The measure of how often a periodic event occurs, such as a signal going through a complete cycle. frequency is usually measured in hertz (hz), with 1 hz equaling 1 occurrence (cycle) per second. frequency is also measured in kilohertz (khz, or 1,000 hz), megahertz (mhz, or 1,000 khz), gigahertz (ghz, or 1,000 mhz), or terahertz (thz, or 1,000 ghz).
- The number of events divided by the reach of the events.
- In uniform circular motion or in any periodic motion, the number of revolutions or cycles completed in unit time. friction false-twist texturing: see texturing, false-twist method.
- The number of repetitions per unit time of a complete waveform, expressed in
- The rate of vibration for a light wave or other electromagnetic wave
- The number of times a specified event occurs within a specified interval (e.g. accidents per year).
- Frequency in uniform circular motion or in any periodic motion is the number of revolutions or cycles completed in unit time. the international systems of units expresses frequency in hertz (1 hz = 1 cycle per second).
- Number of complete wave cycles passing a given point per second or the number of vibrations per second. frequency, fundamental: in resonance testing, the frequency at which the wavelength is twice the thickness of the test material. frequency, pulse repetition: number of pulses per second. frequency, response: amplification (gain) of a receiver over a range of frequencies. frequency, test: in ultrasonic testing, the nominal wave frequency in a given test.
- Number of times per second that a cyclical waveform repeats. the unit of frequency is hertz (hz).
- Number of times per second that a cyclical waveform repeats. the unit of frequency is hertz (hz). g
- Number of times per second that a cyclical waveform repeats. the unit of frequency is hertz (hz). full-wave current: single-phase or three-phase alternating current converted to produce unidirectional current. rectified current contains more amplitude variation, or ripple, than direct current from a battery.
- Number of complete wave cycles passing a given point per second or the number of vibrations per second.7
- A term used in ellipse to indicate certain periods or durations. used in calculations within some ellipse modules.
