Ins and Outs of Digital Filter Design and Implementation Issue 78



Filters are a key part of any signal-
processing system, and as
modern applications have
grown more complex, so has
filter design. FPGAs provide
the ability to design and implement filters
with performance characteristics that
would be very difficulty to re-create with
analog methods. What’s more, these digital
filters are immune to certain issues that
plague analog implementations, notably
component drift and tolerances (over temperature,
aging and radiation, for high-reliability
applications). These analog effects
significantly degrade the filter performance,
especially in areas such as passband ripple.
