transmitter

(noun)

An electronic device that generates and amplifies a carrier wave, modulates it with a meaningful signal derived from speech, music, TV or other sources, and broadcasts the resulting signal from an antenna.

Examples of transmitter in the following topics:

  • Antennae

    • Usually, it is used with a radio transmitter or radio receiver.
    • In transmission, a radio transmitter supplies an oscillating radio frequency electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves).
    • Antennas may also include reflective or directive elements or surfaces not connected to the transmitter or receiver, such as parasitic elements, parabolic reflectors, or horns.

  • Doppler Effect

    • We have a radio transmitter in the primed frame radiating at a frequency $\omega'$.

  • Reflection and Transmission

    • A wave experiences partial transmittance and partial reflectance when the medium through which it travels suddenly changes.

  • Synaptic Plasticity

    • Short-term synaptic enhancement results from more synaptic terminals releasing transmitters in response to presynaptic action potentials.
    • Synapses will strengthen for a short time because of either an increase in size of the readily- releasable pool of packaged transmitter or an increase in the amount of packaged transmitter released in response to each action potential.

  • Categorical REGE for geodesic distances (Padgett's marriage data)

    • This causes a problem for regular equivalence analysis, because all actors (except isolates) are "equivalent" as "transmitters."

  • Microwaves

    • This frequency range is used for most radar transmitters, microwave ovens, wireless LANs, cell phones, satellite communication, microwave radio relay links, and numerous short range terrestrial data links.
    • A clear line of sight between transmitter and receiver is needed because of the short wavelengths involved.

  • Infrared Waves

    • This is a plot of Earth's atmospheric transmittance (or opacity) to various wavelengths of electromagnetic radiation.

  • Ultraviolet Light

    • This is a plot of Earth's atmospheric opacity (opposite of transmittance) to various wavelengths of electromagnetic radiation, including visible light.

  • Visible Light

    • This is a plot of Earth's atmospheric transmittance (or opacity) to various wavelengths of electromagnetic radiation.

  • Applications of Hyperbolas

    • Such problems are important in navigation, particularly on water; a ship can locate its position from the difference in arrival times of signals from GPS transmitters.
    • A ship can locate its position using the arrival times of signals from GPS transmitters.
