  • Hertz - Wikipedia
    Radio frequency radiation is usually measured in kilohertz (kHz), megahertz (MHz), or gigahertz (GHz), with the latter known as microwaves
  • Kilohertz Definition - What does kilohertz measure? - TechTerms. com
    Since one hertz is one cycle per second, one kilohertz is equal to 1,000 cycles per second Kilohertz is commonly used to measure the frequencies of sound waves, since the audible spectrum of sound frequencies is between 20 Hz and 20 kHz
  • KILOHERTZ Definition Meaning - Merriam-Webster
    If your favorite AM radio station has a frequency of 680 kilohertz (kHz), that means the station's transmitter is oscillating (vibrating) at a rate of 680,000 cycles per second (i e , 680,000 times a second) A related term is megahertz (MHz), meaning " millions of cycles per second"
  • Definition of Hertz, Kilohertz, Megahertz, Gigahertz, Terahertz
    Our table (below) provides definitions of various frequencies or oscillation rates expressed in kilohertz, megahertz, gigahertz, or terahertz
  • Kilohertz - Formula, Differences, Usages, Examples
    The kilohertz is a unit used to measure how often a periodic event, like a wave, happens in a second One kilohertz equals one thousand times per second
  • What is the difference between hertz and kilohertz? - Physics Network
    The kilohertz, abbreviated kHz or KHz*, is a unit of alternating current (AC) or electromagnetic (EM) wave frequency equal to one thousand hertz (1,000 Hz) The unit is also used in measurements or statements of signal bandwidth
  • What is Kilohertz? - Computer Hope
    Kilohertz is a unit of measurement for alternating current, audio signals, and a measurement of wireless signals With circuits, an oscillator circuit supplies a small amount of electricity to a crystal each second that is measured in kHz, MHz, or GHz
  • KILOHERTZ | English meaning - Cambridge Dictionary
    It operates at 930 kilohertz, with a daytime power of 5,000 watts non-directional, and 500 watts directional at night The unit "kilohertz" was not introduced until 1960 The self-quenching frequency was ten kilohertz, just above the highest audio frequency the headphone could reproduce
  • What is a Kilohertz (KHz) Frequency? - videoexpertsgroup. com
    A kilohertz (KHz) is a unit of frequency equal to one thousand hertz (Hz) The hertz (Hz) measures the number of cycles (or oscillations) that occur in one second For example, if a signal oscillates 1,000 times per second, it has a frequency of 1 KHz
  • KILOHERTZ Definition Meaning | Dictionary. com
    Kilohertz definition: a unit of frequency, equal to 1000 cycles per second kHz See examples of KILOHERTZ used in a sentence
