- ABSTRACT:
-
Hybrid form FIR filters have been shown to provide a
trade-off between the direct form and transposed
direct form FIR filters resulting in a low power
implementation. However, the use of multiple constant
multiplication (MCM) techniques is less advantageous
as it results in several MCM blocks. In this work a
method of implementing low-complexity hybrid form FIR
filters using matrix multiple constant multiplication
blocks is proposed. The utilized filter structure can
be seen as a polyphase decomposition with common delay
lines for the subfilters.
