For a message signal ?(?)=2cos100?(?)+18cos2000??
Write the expression for ???⁡(?)⁡???⁡???⁡(?). Consider amplitude of modulated signal as A=10. Also,⁡??(?)=106, ??=1000? and⁡??=1.
Hint: For determining ???⁡(?) , use the indefinite integral of ?(?), i.e., take the value of integral at ?=−∞ to be zero

Generate a Matlab Code for amplitude modulated signal by multiplying a message signal (a low frequency cosine signal) with a carrier signal (a high frequency cosine signal). Sketch the Fourier transform of the modulated signal. Demodulate the modulated signal (with no noise) by again multiplying it with the same carrier signal. Sketch the Fourier transform of the signal obtained in c). Your task is to recover the message signal from the signal in c). Determine the type of filter you...
