Amplifiers and Signal Conditioners

WithRamón Pallás-Areny

Signals from sensors do not usually have suitable characteristics for display, recording, transmission, or further processing. For example, they may lack the amplitude, power, level, or bandwidth required, or they may carry superimposed interference that masks the desired information. Further, implementing other functions such as amplitude demodulation, linearization, and temperature compensation before digitizing signals can sometimes be cost effective.
