App note from Analog Devices on robust precision signal conditioning. Link here (PDF)
Industrial measurement and control systems often need to interface to sensors while operating in noisy environments. Because sensors typically generate very small electrical signals, extracting their output from the noise can be challenging. Applying signal conditioning techniques, such as amplification and filtering, can aid in the extraction of the signal because these techniques increase the sensitivity of the system. The signal can then be scaled and shifted to take full advantage of high performance ADCs.
