The object of this Chapter is acquaintance with the construction of modern analog electronic signal conditioners, that is, devices placed between a signal source and a readout instrument to change the signal. Examples of readout instruments are various sensors, such as mechanic pressure, displacement, and temperature sensors. In fact, in all previous chapters we already considered devices intended for signal conditioning. In this Chapter, these devices are considered not separately, but in the interaction with each other, and the problems of their mutual influence and optimal interfacing are investigated.
For in-depth understanding of the material presented, the readers should first study the previous chapters of this book and be familiar with, in particular, linear devices, detectors, and signal generators.
Upon learning this Chapter, the readers will understand the operation of signal conditioners, be able to properly apply them, and determine the parameters and characteristics for application with a particular sensor.
