Abstract
Filters are essential building blocks of instrumentation schemes; they serve a variety of purposes at different locations in the scheme: -
-
Band limiting and improving the signal to noise ratio
-
band limiting before sampling to minimize aliasing errors
-
picking out a frequency component or suppressing a selected frequency component from a signal
-
restricting the band of frequencies retained after modulation or demodulation
