Operations-on-audio-signal

Spectrum Internship/ Task-2 of MATLAB Write a program in MATLAB that will modulate and de-modulate a signal and plot it accordingly. Follow the steps

1. First ask the user to start the recording, and save that recording in a file.*audio must be of 10 sec.
2. Then use that file and a carrier signal to modulate .*take the Carrier signal as per your wish.
3. After modulating it de-modulate the modulated signal to get the same input signal .
4. Plot 4 signal :- I. Input signal(your voice) II. Carrier signal III. Modulated signal VI. De-modulated signal
5. And after a pause of 5 sec play the demodulated signal in the background.
