Hello friends,

I have got some answers from comp.dsp, and I am thankful.
But still some questions remain:

       1: I have got some combinations for 44.1<->48 sampling converter
          like:

             3:2,  7:5, 7:16 or
             7:8,  3:5, 7:4  or
             3:10, 7:4, 7:4 

          The true factorization gives us:

           44.1   147     3*7*7
          ------=------=-----------
            48    160   2*2*2*2*2*5


          If your answer is yes, which one is better?.
              
                       In the book of
            ( Multirate Digital Signal Processing     
               By  Crochiere and L.R. Rabiner),
               They do not mentioned the way of optimizing the process
               for L:M in general. They only discuss for Decimator or 
               Interpolator.(Not both together)

       2: What kind of filters would be in most efficiency in this 
               application?.
          Windowed ones, polyphase ones, IIR ones , ...?

Thank you all.

Kaamy
