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)
What is an carrier amplifier?
It is a direct-current amplifier in which the dc input signal is filtered by a low-pass filter, then used to modulate a carrier so it can be amplified conventionally as an alternating-current signal; the amplified dc output is obtained by rectifying and filtering the rectified carrier signal.
When a carrier is phase modulated with an integrated modulating signal the resultant is?
It gives frequency modulated signal
What is the purpose of carrier signal in modulation?
Carrier signal is of high frequencies, it gives strength to the original signal because original signal cannot travel long distances so it needs to be strengthen a bit for transmitting. The carrier signal is a high frequency signal, called an RF. Radio Frequency signal, it is to high for the human or animal ear to detect it, so its outside the audible spectrum and can easily be transmitted over the air to receivers that is tuned to receive that frequency and detect any modulation on that signal.
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.

Why carrier signal is always in analog signal?
It isn't always. Baseband analog signals have no carrier.
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.
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
Why is the intelligence signal not in the AM envelope?
The intelligence signal is in the AM envelope.In AM modulation, the carrier is amplitude modulated by the signal. This signal appears as the envelope of the carrier. You can demodulate it by following the peaks on each cycle of the carrier. You can either follow the positive peaks or the negative peaks - it does not matter if the original modulation is symmetrical.
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
What cell phone carrier has the weakest signal?
The cell phone carrier that has the weakest signal varies by the market that you live in and even sometimes your location on your street. In the Utah area the carrier with the weakest signal is T-Mobile but that changes if you go to another area.
What converts analog signal information into an analog carrier signal?
Analog Modulation
What is signal modulation?
modulating signal is the message to be carried by the carrier signal.
What is the frequency and wave form of old land line phone carrier?
First answer.The landline phone has no carrier frequency it is a baseband signal with a 3KHz bandwidth.Correction:So there is a signal that can handle a 3KHz bandwidth, what do you call that signal? I call it a carrier, if you don't have a carrier, you will need to amplify the audio every 30 meters else you will end up with no audio at the end of the line. So there is a carrier on all phone lines. Note the carrier signal are up to 90 VPP and is AM modulated at the instrument, but in digital systems the carrier are switched on and of, FSK modulation.
The speed of a t carrier depends on its?
the speed of a T carrier depends on its signal level
What is an carrier amplifier?
It is a direct-current amplifier in which the dc input signal is filtered by a low-pass filter, then used to modulate a carrier so it can be amplified conventionally as an alternating-current signal; the amplified dc output is obtained by rectifying and filtering the rectified carrier signal.
