FDM is a technique in which analog signals are transmitted as single bandwidth signal in which each information signal shares bandwidth. FDM is the process to utilize the bandwidth in which as many as possible information signals are transmitted.
First of all information signals are modulated (any modulation AM OR Angle) then they are multiplexed (which is addition of all information signals) and then each signal is filtered with band-pass filter to separate each signal from composite signal. In last we have demodulation of any type to recover original message signal.
In this code Band-pass filters are designed with Filter Designer of MATLAB.
Cutoff frequencies are as f1 = (fc-fm) and f2=(fc+fm), where fc carrier frequency and fm is signal frequency.
NOTE: To run code first export filters from filter designer to MATLAB workspace then you go for code.
