NOISE AND ITS ROLE IN INSTRUMENTATION

The role of noise in instrumentation is examined. Generally, the presence of noise limits the sensitivity of a measurement. Various methods of improving the signal-to-noise ratio are described. However, another facet of noise in measurement systems is that it can be used as a measurement tool. This...

Zusammenfassung:The role of noise in instrumentation is examined. Generally, the presence of noise limits the sensitivity of a measurement. Various methods of improving the signal-to-noise ratio are described. However, another facet of noise in measurement systems is that it can be used as a measurement tool. This aspect is also examined and some examples of the use of noise in instrumentation are presented.
