SENSOR SIGNAL CONDITIONING: Overview
Signal conditioning is one of the most important -- and most overlooked -- components of a data acquisition system. Most signals require some form of preparation before they can be digitized, for example thermocouple signals must be amplified before they can be digitized. Other sensors, such as RTDs, thermistors, strain gauges, and accelerometers, require electrical power to operate. Even pure voltage signals can require special technologies for blocking large common-mode signals or for safely measuring high voltages. All these preparation technologies are forms of signal conditioning. Common types of signal conditioning are: Amplification, Attenuation, Isolation, Multiplexing, Filtering, Excitation, Linearization, Cold-Junction Compensation and Simultaneous Sampling.

SENSOR SIGNAL CONDITIONING: Blogs
By Richard Mourn, Quantum Parametrics LLC The 1394 (FireWire) audio-video standard has long been popular in computer and consumer electronics applications. I’ve worked on IEEE-1394 since 1992, and almost all of that time was spent focused on consumer electronics products such as camcorders, PC hosts, HDD/DVD systems, digital television, and set top boxes. Now, 1394 is moving into...
