Help me solve all of the following questions pleasejQuery22408112556010643408_1621001692063?

Please help the Matlab code to this communication system problem. I'm given the following information and asked to use Matlab to demodulate the signal non-coherently and use MATLAB to play the audio signal. Any help will be greatly appreciated.

am: This vector is the discrete time signal obtained by sampling the AM-DSB-FC signal s(t), i.e., am[n] = s(nT). The signal s(t) is the result of AM modulating an audio signal of human speech, m(t).

The given Matlab vector is 1200000x1.

Fs is the sampling rate for am in samples per second, i.e., Fs = 1/T.

Fs = 80000

fc is the carrier frequency for am, in Hz.

fc = 20000

Given Hints: load, lowpass, sound, and sqrt

m(t) is a recording of human speech. It has a bandwidth of about 3 kHz.
