Function Of Modem Is Modulation And Demodulation
Matlab has a built-in function called "demod" in the communications (signal processing) toolbox where you can specify 'fm' for frequency 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.
The full form of Modem is Modulator-demodulator. Modulation is process of converting the digital computer signals to analog telephone signals. Demodulation is the opposite conversion, analog to digital.
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.
Carrier signals that carry information by the process of frequency- or phase-modulation.

Demodulation means converting the sounds or signals received by the modem back into data that is usable by the computer.
Uhhh . . . the answer is . . . "Population?"
The main function of baseband is to process and control the transmission and reception of digital signals within a communication system. It is responsible for tasks such as converting analog signals to digital, coding and decoding data, and managing signal modulation and demodulation. Overall, the baseband plays a crucial role in enabling efficient communication between devices.
The mixer in an AM receiver combines the incoming radio frequency (RF) signal with a local oscillator signal to produce an intermediate frequency (IF) signal. This process allows for easier amplification and filtering of the desired audio signal, as the IF is typically at a lower frequency. The mixer effectively translates the high-frequency AM signal down to a more manageable frequency for further processing, enabling clearer audio reception.
