Abstract :
The use of peak-to-peak values in describing output noise of a magnetometer or low frequency amplifier is of questionable value for certain applications. A more precise statement of instrument noise is made with a plot of the noise power spectral density versus frequency. The spectral density plot provides a rich source of information which can be used in the selection and testing of such instrumentation.
