Signal averaging Chapter 15 15.1 Measuring signals in the presence of noise
... When measuring a small but steady signal in the presence of random noise we can often improve the accuracy of the result by making a number of measurements and taking their average. This approach has the great advantage that it is easy to do — given enough time — but it cannot overcome all of the pr ...
