The use of high frequencies for carrier waves in communications permits a higher rate of information transfer than could be accomplished with lower frequencies. The higher frequencies have the potential for higher "data density" or "information density" than lower frequencies.

What is the use of CVT in substations?
A CVT in substations uses it as a communication system. It is also use in filtering high frequency waves that acts as a carrier network.
What is the use of pilot carrier in ssb?
to make available carrier frequency at the receiver
Do cells phones interfer with wireless microphones?
All communication systems use electromagentic waves which by the law of Superposition of Waves travel independently in any meadium and hence do not interfere but if the frequencies tend to match then the carrier waves with amplitude modulation are more affected and give poor quality sound at the receiving end than the frequency modulated carrier waves.
The name for the use of high frequency sound waves in an imaging process that is used to diagnose patient illness is?
ultrasound
Why we use the carrier frequency?
The carrier frequency, as the name implies, "carries" the actual signal to be transmitted. Exactly how this is done depends on the technology being used. At the other end, the receiver subtracts out (don't take that too literally; again, it depends on the technology used) the carrier frequency, and what's left is the desired signal.
Which kinds of sound waves can be produced by bats?
Bats produce high frequency (also known as ultrasonic) sound waves, which they use as a type of sonar, to locate insects in the air.
What is use of color burst signal?
for colour sub carrier frequency
What are the three components of electromagnetic waves that are used to describe them?
from high frequency to low you have: gamma, x-rays, ultraviolet, visible light, infrared, microwaves, radio waves
What is the relation between carrier frequency and modulating signal?
If the modulating system is AM (Amplitude Modulation) then the amplitude of the carrier wave changes with the amplitude of the modulation. On a specrum analyser that shows up as frequency sidebands. If the frequency of the carrier waves depends on the amplitude of the modulating signal that is called FM (frequency modulation). On a spectrum analyser that shows up as sidebands also.
How does submarines talk to each other?
They use the power of Puff the magic dragon's fart which sends high frequency waves to each submarine.
How does the frequency of the waves compare in the two diagrams?
use an ruler
What is carrier frequency?
A carrier frequency is a single radio frequency with steady amplitude. Alone, it would sound like silence on a receiver. This is the frequency that a radio receiver is tuned into. To be of use in communication, this carrier wave has to be changed in time with another signal (usually audio), called 'Modulation' It can be turned on and off using a Morse key. It can be changed by shifting the frequency, FM. It can be changed by varying the amplitude, AM. It can be changed by adding or subtracting audio to the carrier. Single Side Band. It can have data applied by shifting between two carrier frequencies. FSK. (Frequency shift keying.) It's called a carrier, because it is the carrier of information without necessarily being the information itself.
