[cs615asa] Question about wrap

[Chih-Yuan Lee]

Dear professor,

I found some  of the input rate or output rate are negative.

So I tried to find some articles from google about why the value is 
negative.

They said if the value(t)-value(t-1) is negative the counter has 
wrapped. So the formula will be different. 

Would you please tell us some information about 32 bit counter and 64 
bit counter?? 

And do we need to consider this kind of situation? Can we just  replace 
negative value by positive value like using " absolute value "??

Thanks,
Chih-Yuan Lee
