to shift the frequency of information signal ,at the frequency domain to a higher frequency ...so the information can be transmitted to the receiver .
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.
If the frequency of the oncoming generator is slightly higher than the system frequency, the phase angle between the system and generator voltages will slowly change at a frequency equal to the difference between system and generator frequencies.
Gain crossover frequency is the frequency at which a system's magnitude is equal to unity, or 1.
Telestimulation systems are described for chronic indirect muscle stimulation in caged rabbits and mice. Both system use a 5 MHz carrier frequency transmission and consist of a transmitter and a receiver. The latter is fixed to the back of the animal.
when the load on a certain system increases the frequency of the system falls normally. It is dangerous to operate the equipments when the frequency is lower than the normal rated frequency so shed the when the frequency falls under voltage relays are used. I hope i answered your question :)
Carrier is itself a High frequency signal,both are same my friend if you still have doubt your welcome.

The optimal frequency required for peak performance in this system is 2.4 GHz.
Deviation ratio: In a frequency modulation system, the ratio of the maximum frequency deviation of the carrier to the maximum modulating frequency of the system under specified conditions
Deviation ratio: In a frequency modulation system, the ratio of the maximum frequency deviation of the carrier to the maximum modulating frequency of the system under specified conditions
Need for modulation: 1. Length of the antenna for a transmitter is inversly proportional to the frequency of the signal to be transmitted. So we try shift the frequency of the singal for the transmission to higher frequencies. 2. Every transmission of signal in a bandwidth is assigned with a particular frequency which is attained by modulating the signal with the carrier frequency. Different modulation techniques are implemented according to the requirements and compatibilities

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.
it will affect the output of a receiver only if it falls within the passband.in that case,the carrier and noise voltage will mix and the difference frequency,if audible,will interfere with the reception of the wanted signal..
errrrrrrrrr electrictiy, doesnt that come from the wall?????
Spot frequency refers to the specific frequency at which a signal is transmitted, received, or monitored at a particular moment in time. It is the operating frequency of a communication system or device at a given instant.
