•Use a tool to
establish a prototype design
–MatLab is a
great choice
–See http://doctord.webhop.net/courses/Topics/Matlab/index.htm
for a Matlab tutorial
by Dr. Bouzid Aliane; Chapter 5 is on filter design.
•Check your
design for ringing/overshoot.
–If detrimental, increase the filter order and redesign to exceed the frequency response specifications
–Move poles
near the jw-axis to the left to reduce their
Q
–Check the
resulting filter against your specifications
•Moving poles
to the left will reduce ringing/overshoot,
but degrade the
transition region.
