Filters can be classified in many ways based on the
componets using, implementation etc

Implementation means either analog techniques or digital

In analog the main classification is active and passive
filters

filters made of simple R,L,C elements are refered as
passive filters. when we are using some active components
like opamps, transistor along with passive components it
becomes active filters. the main advantage is that we can
vary the gain and other parameters easly in active filters.

Now depending on the application and neccisity we are going
for the diffreant forms such as low pass, high pass etc.
now we can see that all these filters are made of some
hardware components, so noise is an important factor which
will affects its accuracy.

so noise free design can be accomplished with the help of
digital filters which is based on algorithms. 2 basic forms
of digital filters are FIR and IIR filters. FIR filters can
be designed in many methods , one of such method is
windowing methods. some of IIR filters are butterworth
filter, chebyshev filter(type 1 and 2), cauver filters.


basic approach in design of IIR filter is first design
the filter in analog domain and then transform it into
digital domain

now the latest trend of filters which are widely using in
navigation, control applications is kalman filters
discoverd by R.E kalman.it is an adaptive type filter. it
not only removes the noise but also helps in esimating the
differant states of a system which are not measuable( for
more info kindly go through state space modelling)

filters are classified in different types.
1.passive filters
2.active filters
in passive filters different types based on type of
components are used.
these are
A)RC low pass
B))RC high pass
C)RC band pass
D)RC band reject
in LC type components used
A)LC low pass
B)LC high pass
C)LC band pass
D)LC stop band
2)Active type classified four types
A)Active low pass
B)Active high pass
C)Active band pass
D)Active stop band
