Hi everyone,

I've been working on this thing for the last few days i'm suppose to get a number between 80 and 100 yet i get a number around 2. I'd appreciate if anyone could please tell me what is going on?

void linear ()
{
double xi, yi, ei, n=16.00, N= 1000.00, xi_sq=0.00, e_sq=0.00, rms_xi, rms_e, qsnr,test,test1=0.00;
for (int i=0; i<N; i++)
{
//first check if xi is x less than or equal to 1 or larger than or equall to -1
xi=((2*i)/ N)-1;
if ((xi>1) || (xi<-1))
cout << "not within a valid interval" <<endl;
else
{
xi_sq= xi_sq + pow(xi,2);
yi= xi * pow(2,n-1);
ei=fabs(yi-round(yi));
e_sq= e_sq + pow(ei,2);
}
}
test= fabs(xi_sq)/N;
rms_xi= sqrt(test);
rms_e=sqrt(e_sq/N);
qsnr= rms_xi/rms_e;
cout <<"linear result is "<<qsnr<<endl;
}
