Practical_firdesign
This tutorial white-paper illustrates practical aspects of FIR
filter design and fixed-point implementation along with the
algorithms available in the Filter Design Toolbox and the
Signal Processing Toolbox for this purpose.
The emphasis is mostly on lowpass filters, but many of the
results apply to other filter types as well.
The tutorial focuses on practical aspects of filter design
and implementation, and on the advantages and disadvantages
of the different design algorithms. The theory behind
the design algorithms is avoided except when needed to motivate
them.
