+# 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.
