Why is amplitude modulation susceptible to noise but not frequency modulation?
because noise usually changes the amplitude not frequency.
When modulation frequency is doubled modulation index also doubled in case of FM or pm or am?
In Frequency Modulation (FM), if the modulation frequency is doubled, the modulation index does not necessarily double; it depends on the amplitude of the modulating signal. In Amplitude Modulation (AM), the modulation index is defined as the ratio of the peak amplitude of the modulating signal to the carrier amplitude, so it remains unchanged with varying modulation frequency. For Phase Modulation (PM), similar to FM, the modulation index is influenced by the amplitude of the modulating signal and does not inherently double with the modulation frequency. Thus, modulation frequency and modulation index are not directly linked in this way for FM, PM, or AM.
What is the modulating frequency of amplitude modulation?
the frequency range of an am wave is 20herz to 20kilo herz
In which Analog to analog modulation methods does the peak amplitude?
Frequency modulation Phase modulation
What is changing amplitude or frequency called?
modulation
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
Amplitude modulation and frequency modulation range in India?
Normal frequency range for amplitude modulation is 550kHz to 1610kHz
What does AM and FM mean?
am is amplitude modulation, fm, frequency modulation
Why is amplitude modulation susceptible to noise but not frequency modulation?
because noise usually changes the amplitude not frequency.
What are the advantages frequency modulation amplitude modulation?
Frequency modulation have some advantages over amplitude modulation, FM is not sensitive to the amplitude noise, and have high efficient use of transmitted power
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 are FM and AM?
Amplitude Modulation (AM) Frequency Modulation (FM)
In FM does the amplitude remains constant?
In frequency modulation (FM) the amplitude does not remain constant. Instead, the amplitude varies according to the modulation index and the frequency of the modulating signal. This is in contrast to amplitude modulation (AM), where the amplitude of the carrier signal is modulated while the frequency remains constant.
What does the frequency AM stand for?
amplitude modulation
What does AM and FM stand for in music?
amplitude modulation & 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
