Chapter 12. Signal Processing and Conditioning
Typically a sensor cannot be directly connected to the instruments that record, monitor, or process its signal, because the signal may be incompatible or may be too weak and/or noisy. The signal must be conditioned—that is, cleaned up, amplified, and put into a compatible format.
The following sections discuss the important aspects of sensor signal conditioning.
12.1. Conditioning Bridge Circuits
12.1.1. Introduction
This section discusses the fundamental concepts of bridge circuits.
Resistive elements are some of the most common sensors. They are inexpensive to manufacture and relatively easy to interface with signal conditioning circuits. Resistive elements can be made sensitive to temperature, ...
