Programmable 2nd Order low Pass Filter Circuit. The most common filter found in a data acquisition system signal path is a low pass filter. This type of filter is usually used to reduce A/D converter aliasing errors. If there is more than one signal that is applied to the A/D converter through a multiplexer, each signal source may have its own set of filter requirements, i.e. settling time, fast transition region
