Two examples of carrier signals are amplitude modulation (AM) radio waves and frequency modulation (FM) radio waves. In AM, the amplitude of the carrier wave is varied in accordance with the audio signal, while in FM, it is the frequency of the carrier wave that is varied. Both methods are used to transmit audio signals over radio frequencies, enabling communication over long distances.
What else can I help you with?
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.
What kind of transformer whose purpose is to combine audio frequency signals with high frequency carrier signals in a radio transmitter?
The transformer used to combine audio frequency signals with high-frequency carrier signals in a radio transmitter is called a modulation transformer. This type of transformer effectively couples the low-frequency audio signals to the high-frequency RF (radio frequency) carrier, allowing for efficient transmission of the combined signals. It ensures minimal loss and maintains the integrity of both frequency components during the modulation process.
AM signals travel as change in the...?
AM signals travel as changes in the amplitude of the carrier wave. This modulation allows the signal to carry audio information, as variations in the amplitude correspond to the sound waves being transmitted. The frequency of the carrier wave remains constant, while its strength varies to encode the desired information.
Why carrier signal has higher frequency than message signal?
Carrier signals have higher frequencies than message signals to effectively transmit information over long distances and through various media. The higher frequency allows for better modulation techniques, which help to reduce interference and increase the capacity for multiple signals to be transmitted simultaneously (multiplexing). Additionally, higher frequency signals can be more easily directed and are less susceptible to noise, ensuring clearer reception of the underlying message signal.
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.
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.
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.
What are two examples of communication technology?
house phone,pay phone,cell phone
