Understanding polyphase filtering

Hello!

1)What is the relationship between a multirate filter, polyphase filter & FIR filter?
My understanding is filters are used to suppress aliasing in decimators. Nonrecursive nature of FIR filters can significantly improve the overall efficiency of FIR decimators.

This chapter probably contains the answers to your question (although I think it's worth to read through the entire book).
