What is Am modulation?
AM imply amplitude modulation of a carrier signal
What is signal modulation?
modulating signal is the message to be carried by the carrier signal.
List two differences between information signal and carrier signal.?
A: A carrier carry information by modulation either Amplitude or Frequency modulation. Therefore AM and FM RADIO M stand for modulation
Why phase modulation is used?
Actually phase modulation was used for the color signal in all analog TV systems.Phase modulation, with some signal preprocessing, was used to indirectly get frequency modulation in many FM transmitters.Certain modems use phase amplitude modulation.etc.
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.
What is Am modulation?
AM imply amplitude modulation of a carrier signal
What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
What is the difference between analog and digital modulation Does it depends on baseband signal?
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
Multiple choice question answer of AM modulation?
amplitude modulation is where we modulate our signal with a carrier signal amplitude changes but frequency remains constant in amplitude modulation
Comparison of amplitude modulation and frequency modulation?
Amplitude of the (high frequency) Carrier signal is varied with respect to low frequency of message signal is called amplitude modulation. Frequency of the carrier signal is varied with respect to low frequency of message signal is called frequency modulation.
What is signal modulation?
modulating signal is the message to be carried by the carrier signal.
What is modulation in data communication?
Data modulation is a method of Electronic packing of data. In Data communication data is transmitted through a process which is called "Data Modulation".
Explain the term modulation. how does it help in data communication?
Modulation is the addition of information to an electronic or optical signal carrier. The modulation can be applied by turning the signal on and off.
What is lowlevel amplitude modulation and highlevel amplitude modulation?
low level amplitude modulation occurs when the carrier signal is first modulated and then amplified,whereas in high level modulation,the carrier signal is first amplified and then is modulated.
List two differences between information signal and carrier signal.?
A: A carrier carry information by modulation either Amplitude or Frequency modulation. Therefore AM and FM RADIO M stand for modulation
What is the mean of AM signal?
Amplitude Modulation
Why is Angle Modulation called nonlinear modulation?
angle modulation is called non linear modulation because the information is stored in phase of the carrier signal
