What is separating the information ofthe signal from the carrier wave?
demodulation
What is bandwidth required for AM signal?
With full double sideband AM the bandwidth of the modulated signal is twice that of the baseband information signal. With suppressed carrier single sideband AM the bandwidth of the modulated signal is identical to that of the baseband information signal. With vestigial sideband AM the bandwidth of the modulated signal is somewhere between the above two cases, depending on how much of the vestigial sideband is included.
What the difference between single side band single carrier transmission and full carrier AM?
1. Single-sideband transmission requires only half as much bandwidth as double sideband.2. SSBSC require less total transmitted power than full carrier AMIn full carrier AM, the transmitted signal consists of two sidebands (containing the transmitted information) and the carrier signal. Long ago, it was realized that both sidebands contained the same information, and the carrier signal could be supplied by the receiver. Thus, if you suppress transmitting the carrier and one sideband, you can use the available power to increase the power in the remaining sideband.
Why carrier signal is always in analog signal?
It isn't always. Baseband analog signals have no carrier.
What is a demodulator?
The process of separating the original information or SIGNAL from the MODULATED CARRIER. In the case of AMPLITUDE or FREQUENCY MODULATION it involves a device, called a demodulator or detector, which produces a signal corresponding to the instantaneous changes in amplitude or frequency, respectively. This signal corresponds to the original modulating signal
What is the difference between SINR and CINR?
SINR - Signal to Interference and Noise Ratio CINR - Carrier to Interference and Noise Ratio difference between those to is difference between carrier and signal carrier is signal who doesn't "carry" any information . it must be modulated( by phase,freq or amplitude) and those changes convey information. carrier is unmodulated signal signal is defined as useful signal which carries information SINR is power of signal to power of interfenence and noise ratio
When does Carrier Signal occur?
The carrier signal occurs at the beginning to transmit information.
What are the difference between carrier signal modulating signal modulated signal baseband and passband?
carrier signal- use for the purpose of conveying information. modulating signal- causes variations in some characteristics of carrier signal. modulated signal - carrier signal after altration in its characteristics is called modulated signal. example- if you want to see an object (suppose it is an modulating signal),you need light(light is carrier signal) and when light will reflect on object you will be able to see if (that is modulated signal)
How receiver detect that which is information signal and which is carrier signal and how it separate both at destination?
carrier is constant frequency information is a change from that constant
What is difference between modulated wave and carrier wave?
Carrier Wave: A carrier wave is a high-frequency electromagnetic wave that is used as the "carrier" or the base signal in a modulation process. It is typically a pure sine wave with a constant frequency and amplitude. The carrier wave by itself does not carry any information; it serves as a vehicle to carry the information from one location to another. In AM and FM radio broadcasting, the carrier wave is the primary signal transmitted by the radio station. Modulated Wave: A modulated wave is the result of combining the carrier wave with an information signal, such as an audio signal or data. Modulation is the process of varying the characteristics of the carrier wave (either its amplitude or frequency) in accordance with the information signal. There are two common types of modulation: Amplitude Modulation (AM) and Frequency Modulation (FM). In AM, the amplitude of the carrier wave is varied in proportion to the amplitude of the information signal. This variation encodes the information onto the carrier wave. In FM, the frequency of the carrier wave is varied in proportion to the amplitude of the information signal. This variation encodes the information onto the carrier wave. The modulated wave contains the information that needs to be transmitted, and it can be demodulated at the receiving end to retrieve the original information.
What converts analog signal information into an analog carrier signal?
Analog Modulation
What is separating the information ofthe signal from the carrier wave?
demodulation
Is carrier signal present at output of double side band suppressed carrier?
No, the carrier signal is not present at the output of double side band suppressed carrier. That is what suppressed carrier means. However, the receiver has enough information to regenerate the carrier if need be. The advantage of suppressed carrier mode is that more power can be deployed to the signal-carrying portion of the modulated carrier.
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 bandwidth required for AM signal?
With full double sideband AM the bandwidth of the modulated signal is twice that of the baseband information signal. With suppressed carrier single sideband AM the bandwidth of the modulated signal is identical to that of the baseband information signal. With vestigial sideband AM the bandwidth of the modulated signal is somewhere between the above two cases, depending on how much of the vestigial sideband is included.
What the difference between single side band single carrier transmission and full carrier AM?
1. Single-sideband transmission requires only half as much bandwidth as double sideband.2. SSBSC require less total transmitted power than full carrier AMIn full carrier AM, the transmitted signal consists of two sidebands (containing the transmitted information) and the carrier signal. Long ago, it was realized that both sidebands contained the same information, and the carrier signal could be supplied by the receiver. Thus, if you suppress transmitting the carrier and one sideband, you can use the available power to increase the power in the remaining sideband.
What does the term carrier mean in science?
A base signal that is modulated with the information being transmitted.
