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.
1.Simple circut 2.No need of demodulation
demodulation or detection.

modem
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.
Matlab has a built-in function called "demod" in the communications (signal processing) toolbox where you can specify 'fm' for frequency demodulation.
