What is the modulating frequency of amplitude modulation?
the frequency range of an am wave is 20herz to 20kilo herz
When signal amplitude is equal to carrier amplitude then modulation index is?
amplitude modulating signal
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 signal modulation?
modulating signal is the message to be carried by the carrier signal.
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.

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.
When signal amplitude is equal to carrier amplitude then modulation index is?
amplitude modulating signal
In phase modulation the amount of phase shift in the carrier signal depends on the of the modulating signal and the rate of phase shift depends on the of the modulating signal?
Amplitude Frequency

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.

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
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
What is meant by am in radio?
Amplitude Modulation- AM standard Broadcast band. AM is an abbreviation for amplitude modulation,a form of radio transmission in which the carrier radio wave's amplitude is varied according to the strength of the modulating signal(sense).
What is the deviation ratio for frequency modulation?
Deviation ratio: In a frequency modulation system, the ratio of the maximum frequency deviation of the carrier to the maximum modulating frequency of the system under specified conditions
