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 over-modulating condition in term of amplitude modulation?
When your audio modulating signal is larger than your RF carrier amplitude the peak of the modulated carrier will become flat and a distorted audio signal with flattened peaks will be send out from the detector on the receiver side
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.
Webex bandwidth requirements?
Transmission bandwidth depends on modulating signal frequency and carrier frequency
How demodulator works?
a demodulator sole function is to restore the original modulating signal. it works by removing the Carrier

How do you calculate frequency range of double side band modulated signal?
Upper sideband = Carrier frequency + modulating frequencyLower sideband = Carrier frequency - modulating frequency
What is over-modulating condition in term of amplitude modulation?
When your audio modulating signal is larger than your RF carrier amplitude the peak of the modulated carrier will become flat and a distorted audio signal with flattened peaks will be send out from the detector on the receiver side
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.
Why is FM preferred to am in satellite channels?
FM stands for frequency modulation and AM stands for Amplitude modulation. In FM, frequency of a modulating signal is modulated using carrier frequency i.e. more data can be transmitted using a little space and also it is safe to transmit the information while in AM amplitude of a modulating signal is modulated using carrier frequency i.e. more space needed for transmitting the information. That's why we use FM in place of AM
When you do modulation in time domain you get modulated waveform of modulating signal information and carrier. How can you recognize the upper and lower side bands in time domain modulated waveform?
You need modulation signal(carrier) which is a required signal in order to make envelope of time domained signal(target signal). The modulating signal is imposed on modulation signal.This creates envelope of waveform which is modulated(desired) signal. Now, the desired signals uper and lower sideband of signal strictly depends on modulation signal's bandwidth. Max. peak of that signal is uper sideband and min. peak is lower sideband for this modulated signal.

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.
Why analog data have to be modulated onto an analog signal?
For transmission through a radiowave.
What is signal modulation?
modulating signal is the message to be carried by the carrier signal.
Are digital transmissions modulated over a carrier?
yes for transmission of the signal to take place smoothly,digital tranmission needs to be modulated over a carrier
Frequency spectrum analysis of AM wave?
An amplitude modulated signal consists of a CW (continuous wave) at the carrier frequency, plus two components for each frequency in the modulating information. The two components are separated from the carrier by a frequency equal to the modulating frequency, with one above and one below the carrier frequency. Thus, the modulating information appears twice in the spectrum of the modulated signal.
