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.
-
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.
-
Wireless Communication
- ., radio transmitters and receivers, remote controls, etc.) that use some form of energy (e.g., radio waves, acoustic energy, etc.) to transfer information without the use of wires.
