What is amplitude modulation derive expression for am wave and modulation index?
the maximum amplitude of carrier wave varied with respect to instantaneous values of message signal is called amplitude modulation
When signal amplitude is equal to carrier amplitude then modulation index is?
amplitude modulating signal
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.
Why normalization of message signal is necessary in conventional amplitude modulation?
to maintain the constant frequency and the phase parameters at the output
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.

the maximum amplitude of carrier wave varied with respect to instantaneous values of message signal is called amplitude modulation
What do you mean 50 percent modulation index?
A(m)/A(c)=0.5 is known as 50% modulation index. where, A(m)=amplitude of message signal A(c)=amplitude of carrier signal
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
When signal amplitude is equal to carrier amplitude then modulation index is?
amplitude modulating signal
What is Am modulation?
AM imply amplitude modulation of a carrier signal
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.
What is the mean of AM signal?
Amplitude Modulation
What is the difference between FM and AM radio waves?
AM means Amplitude(=height) modulation, so the frequency stays the same and the message is coded into variations of the strength of the signal. FM stands for Frequency modulation. Here the strength of the signal stays the same and the message is coded into changes in frequency instead.
What is signal modulation?
modulating signal is the message to be carried by the carrier signal.
Why normalization of message signal is necessary in conventional amplitude modulation?
to maintain the constant frequency and the phase parameters at the output
What is amplitude modulation and frequency modulation and difference between them?
Both angle and amplitude modulation are involved in radio wavelength patterns. Angle modulation is where the modulating wave manipulates the angle of a sine-wave carrier. The two types of angle modulation include frequency and phase modulation. On the other hand, Amplitude modulation is the strength behind carrying the waveform in radio.
