Digital Filters @ Wikipedia
In electronics, a digital filter is any electronic filter that works by performing digital mathematical operations on an intermediate form of a signal.
This is in contrast to older analog filters which work entirely in the analog realm and must rely on physical networks of electronic components (such as resistors, capacitors, transistors, etc.) to achieve the desired filtering effect.
Digital filters can achieve virtually any filtering...

Filter design
Filter design is the process of designing a filter (in the sense in which the term is used in signal processing, statistics, and applied mathematics), often a linear shift-invariant filter, which satisfies a set of requirements, some of which are contradictory.
The problem is to find a realization of the filter which meets each of the requirements to a sufficient degree to make it useful.
The filter design process can be described as an...

Introduction to Digital Filters
Filters are signal conditioners.
Each functions by accepting an input signal, blocking prespecified frequency components, and passing the original signal minus those components to the output.
For example, a typical phone line acts as a filter that limits frequencies to a range considerably smaller than the range of frequencies human beings can hear.
That's why listening to CD-quality music over the phone is not as pleasing to the ear as...
