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.
Why must the oncoming generator on a power system be parralleled at a higher frequency than that of the running system?
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.
What is gain crossover frequency?
Gain crossover frequency is the frequency at which a system's magnitude is equal to unity, or 1.
What is the difference between frequency division multiplexing and freq division multiple access?
The basic difference between fdm and fdma is that fdm is used in wired system where as fdma is used in wireless communication.
What is the need of under frequency relay in load shedding on power system?
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 :)
Why instead of carrier you are utilizing high frequency information signal in communication system?
Carrier is itself a High frequency signal,both are same my friend if you still have doubt your welcome.

What is the frequency deviation for frequency modulation?
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
What is the deviation ratio for frequency modulation?

Need of modulation in communication?
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
Medium required for communication system?
motherboard
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.
In electronic communication system describe the upper side frequency and the lower side frequency?
errrrrrrrrr electrictiy, doesnt that come from the wall?????
What is effect of noise on digital communication system?
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..
What is the Limitation of communication system?
1.Amplitude 2.bandwidth 3.Noise 4.Frequency
What are the elements of radio communication system?
There are many elements of a radio communication system. These elements include a transmitter, radio frequency oscillator, modulator, transmitting ariel, receiving ariel, demodulator, and amplifier.
What is the function of modulator in a communication system?
Modulation is defined as a process by which any characteristics of a wave is varied as a function of the instantaneous value of another wave. The first wave which is a high frequency sine wave is known as carrier wave. Second wave is known as modulating wave and the resultant wave is known as the modulated wave.
