What is the technical difference when it comes to the implementation of AM and FM?
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
What is the modulating frequency of amplitude modulation?
the frequency range of an am wave is 20herz to 20kilo herz
What will happen if frequency of modulating signal is greater than the carrier signal in amplitude modulation?
Then the signal will be the same amplitude.
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 Am modulation?
AM imply amplitude modulation of a carrier signal
Is it true that information can be carried on a carrier wave by changing or modulating either the amplitude or frequency?
in frequency modulation, frequency of carrier signal changes. so frequency variations of carrier convey all the information in frequency 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.
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

The process of changing the strength of a carrier wave?
Amplitude modulation.
What is FM?
FM stands for frequency modulation. The definition is: when the frequency of the carrier wave is changed in accordance with the intensity of the signal, it is called frequency modulation. In frequency modulation, only the frequency of the carrier wave is changed in accordance with the signal. However, the amplitude of the carrier wave remains unchanged.
In which analog-to-analog modulation methods does the peak amplitude of the carrier signal remain unchanged?
Frequency modulation and Phase modulation
What will happen if frequency of modulating signal is greater than the carrier signal in amplitude modulation?
Then the signal will be the same amplitude.
How do amplitude modulation and frequency modulation differ?
Amplitude modulation is where a constant carrier is modulated by the signal, so that the envelope of the carrier represents the signal. Frequency modulation is where a constant carrier is modulated by the signal, so that the frequency of the carrier represents the signal. Phase modulation is where a constant carrier is modulated by the signal, so that the phase angle of the carrier represents the carrier.
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 are the modulation techniques for video signals?
The modulation techniques for video signals include the utilization of the amplitude modulation technique. The amplitude of the carrier wave is made proportional to the video signal voltage. It also utilizes frequency modulation technique.
