_______________________________________________________________________________________
Step 1—Filter Design
Start with the program “PZ” to determine what type of
filter is needed. This helps determine the type
(Butterworth, Chebyshev, etc.) and the number of poles
for the optimum choice. The program also plots the fre-
quency response and calculates the pole/zero (f0) and
Q values for each second-order section. Each
MAX260/MAX261/MAX262 contains two second-order
sections, and devices can be cascaded for higher
order filters.
