Why carrier signal is always in analog signal?
It isn't always. Baseband analog signals have no carrier.
What is Analog carrier system used in telephony?
Analog Carrier System is a transmission system that uses repeaters that compensate for analog medium impairments, and produce output signals that are linear-scaled versions of input signals. Analog carrier systems can carry speech, data, video and supervisory signals although they are best suited for speech signals.
How do you find RMS Error Between Two Signals?
I have two Different Signals, I would like to find the RMS Error Between them, and Mathematically derive how the signals differ from each other. I would like to find the RMS Error for the two Signals. Please Help. Thanks in Advance.
Two signals of 2GHz and 4GHz are frequency modulated on same carrier 10?
Definition: In FM technique, the frequency of the carrier signal changes according to the instantaneous amplitude of the modulating signal. Hence, the frequency of the modulating signal is of irrelevance here and the devition from "fc" will be dependent on the amplitude of the same. considering 2GHz and 4GHz to be digital signal the ratio would be 1:1.
Is mixing the same as amplitude modulation?
No, mixing is adding two signals together, modulation is more like multiplying two signals. IN mixing, the result has the same frequencies as the input signals. In modulation, the result is the sum and difference frequencies.
What does modulation actually do through message and carrier signal?
when the messege and carrier signals are going through a modulator it mixes the two waves ie, it's acts like a mixer and amplified it and send the signals through the air ie its acts like an transmittter. the carrier wave carring the messege signal
What is mien by carrier frequency?
High range of frequency that carries the message signals in transmission of data.after receiving the signals, the detector seperate the message and carrier .
What is the difference between the standard amplitude modulation linear addition and multiplication of signals?
In modulation u r sending two signals but their frequencies are sum or difference of carrier frequency and signal frequency.In addition u send two signals at two different frequencies so more interference.

What Ratio of frequency deviation when Two signals of 2GHz and 4GHz are frequency modulated on same carrier 10 GHz?
No answer is possible as the frequency shift is proportional to the amplitude of the signal at any time. The frequency of the the two input signals is irelevant.
Can a single personal FM receiver receive from two transmitters simultaneously?
Well yes if the carrier frequency are the same. <<>> The FM receiver will lock on to the strongest of the two signals.
Is light the only signal carrier in optical fibers?
Yes, light is the primary signal carrier in optical fibers. It travels through the fiber as pulses of light, typically in the form of laser or LED signals. Other signals such as electrical signals can be converted into light signals at the source and back to electrical signals at the receiving end.
Where does a punctuated need to be in a sentence?
Punctuation guides the flow of written language. Two examples of this are below: A period signals the end of a complete thought. A comma signals a pause.
How do you receive digital signals?
The carrier waves are electromagnetic in nature, and it is the modulation of them that carries the information. There are several methods of modulation, FM, AM, Pulse-code, and many more. The digital signals are modulated on the carrier wave. And digital signals should theoretically be more immune to interference than analog ones.
How can a stolen phone be activated with a different carrier?
It probably can't since the signals are different.
What are two examples of communication technology?
house phone,pay phone,cell phone
