I really need to clear this :),

In real world we sample a signal from A/D suppose with Fs=100 Hz..Now when we see that
digital signal its non uniform sampled. 

Now, on non uniform signal Please correct me if  am wrong:)

i want to apply oversampling which means that i need to sample it again with Fs=400Hz....and later regularise it. But how will  i apply oversampling on it.....I mean i dont have amplitude value or i can say that i dont have signal to sample i only have some non uniform discrete values

How over sampling is apply in the real world. 

1. We always do over sampling during A/D converter
2. Also how can i apply window function, I didnt get reply for this

1.if my orginal signal s is between -30 to 30 Hz 40 by 1
2.And signal on whch filter need to apply is 127 by 1 w
3. Now how can i recover s by applying rectangular window function on w. I mean dimensions are different..its not working on matlab
I am doing 

w.*RECTWIN(SIZE(s))

Any help will be appreciated 
Thanks
