Question

I need someone to code this up in C , and show the screen shot shot of the output for some input

Design an amplitude modulation scheme that will generate the amplitude modulated signal yAM(t) ct)m(t)c(t) where c(t) sin 2rFd is the carrier with carrier frequency F, and m(t)-A,n sin 2πFmt is the modulating signal with amplitude Am and modulating frequency Fm. For initial values you may assume that Fc-6 kHz, Fm-400 Hz and Am-1.

Answer 1

#include<stdio.h>
#include<math.h>
#include <stdlib.h>
#define PI 3.14159265

main()
{
double ret, val,t,am,fc,fm;
t=1/24.0; //if t>=1 vlaue is 0;
fc=6;
fm=0.4;
am=1;
ret = sin(2*PI*fc*t);
val=ret+((am*sin(2*PI*fm*t))*ret);
printf("%lf",val);
}

output:
