Filter Design Procedure
The procedure for most filter designs is to first convert
the required frequency response specifications to f0s
and Qs for the appropriate number of second-order
sections that implement the filter. This can be done by
using design equations or tables in available liter-
ature, or can be conveniently calculated using Maxim's
filter design software. Once the f0s and Qs have been
found, the next step is to turn them into the digital pro-
gram coefficients required by the MAX260/MAX261/
MAX262. An operating mode and clock frequency (or
clock/center frequency ratio) must also be selected.
Next, if the sample rate (fCLK/2) is low enough to cause
significant errors, the selected f0s and Qs should be
corrected to account for sampling effects by using
Figure 20 or Maxim's design software. In most cases,
the sampling errors are small enough to require no cor-
rection, i.e., less than 1%. In any case, with or without
correction, the required f0s and Qs can then be select-
ed from Tables 2 and 3. Maxim's filter design software
