Matlab has a built-in function called "demod" in the communications (signal processing) toolbox where you can specify 'fm' for frequency demodulation.
AM: amplitude modulation
It is a way to see differentences between items. Like: Cow is to barn as elephant is to zoo.
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

demodulation or detection.
modulation and demodulation
modulation and demodulation
MOdulation DEModulation.
its nothing but modulation and demodulation. modulation of the message is done in transmitter side and demodulation is done at receiver side and retrieving the original message.

Function Of Modem Is Modulation And Demodulation
Function Of Modem Is Modulation And Demodulation
MODEM modulation & demodulation .......
Demodulation the opposite is Modulation And when you put them together you get MODEM Modulation/Demodulation = MODEM
Demodulation is needed with modulation becoz modulation it is converting analog to digital signal n we can't understand digital. That's why we require digital to analog converter or demodulator.
In case of coherent demodulation carrier used for demodulation purpose is in phase and frequency synchronism with carrier used for modulation purpose. For non-coherent demodulation it is not in synchronism.
