polyphase decimator in simulink

Started by cfy3...@yahoo.com September 22, 2008
Hi all,

I am trying to implement a polyphase decimator in Simulink environment. The problem I have is, how to relize the 1:n commutator switch? In Simulink, only n:1 switch is available.

Also, is polyphase decimator popular? Seems to me, most people use CIC.
