There is some equivalence between AM and FM, because sinc(x) = sin(x)/x is a sinusoid of decaying amplitude but also a rectangular block of frequencies. If the FM spectrum is approximated by a large number of thin rectangular blocks (i.e. sinc curves), this is also a sum of many sinc curves in the time domain.

What does AM and FM stand for in music?
amplitude modulation & frequency modulation
What is the meaning of FM in FM Radio?
FM means frequency modulation AM means amplitude modulation
What do the letters FM on your radio stand for?
They could mean a lot of things, but in the context of each other they probably stand for Amplitude Modulation and Frequency Modulation (two different methods for sending an audio signal using radio waves) respectively.
What is the difference between am raido and FM radio?
A: AM radio is an Amplitude Modulation transmission . Meaning it has fix frequency but it is modulated by the signal. FM Frequency Modulation the frequency is modulated by the signal
What does the AM in AM Radio stand for?
Amplitude Modulation (AM) and Frequency Modulation (FM) AM tuning changes the amplification size of the waves being received, FM tuning controls the frequency of the waves being received. As commercial radio rose from it's early form, the AM 'band' stood for years as the only type of radio available. As technology improved, engineers discovered that they could modulate 2 channels of higher quality sound inside of one carrier frequency. The Federal Communications Commission designated from 87 MHz to 108 MHz for the new FM format. And, with this, FM radio was born.
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)
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
What is the modulating frequency of amplitude modulation?
the frequency range of an am wave is 20herz to 20kilo herz
What do the initials AM and FM relate to?
AM = Amplitude Modulation. FM = Frequency Modulation
