hi,
You can use the resample function, to get the idea clear here is an example :
Fs1= 999.9917;
Fs2= 99.9976;
t1=0:1/Fs1:0.5-1/Fs1; y1=sin(2*pi*t1*300);
t2=0:1/Fs2:0.5-1/Fs2; y2=sin(2*pi*t2*30);
The resampling function uses two integers p,q to resample y2 by p/q*Fs2 as the new rate, thus Fs1=p/q*Fs2.
[p,q]=rat(Fs1/Fs2);
y3=resample(y2,p,q);
