Assume a function $ x(t) $.
We wish to covert a signal sampled at $ T_1 $ one sampled at $ T_2 $ without having to reconstruct the original $ x(t) $ and then resampling at a new rate.
There are two cases here.
1. $ T_2 $ is a multiple of $ T_1 $
2. $ T_2 $ is a divider of $ T_1 $
To be continued...
