This low-frequency noise characteristic is known as “1/f noise” since the noise power spectral density goes inversely with frequency (actually 1/fg). It has a -1 slope on a log plot (the noise voltage (or current) 1/√f spectral density slopes at - 1/2). The frequency at which ...
Within this framework, a WEP violation introduced by the diagonal elementsr1andr2would emerge as a non-zero differential acceleration proportional tor1−r2; a WEP violation introduced by the off-diagonal elementrwould manifest itself as an excess of phase noise with zero average on the acceleratio...

Using the Allan variance and power spectral density to characterize DC nanovoltmeters When analyzing nanovoltmeter measurements, stochastic serial correlations are often ignored and the experimental standard deviation of the mean is assumed ...
The concept of structure functions, which is an extension of the variance approach, is useful to determine the variance (the structure function) which is optimized for a type of noise and for an order of drift. The multivariance method was developed to use different variances over the same sig...

Zero span is sometimes used for other noise and noise-like measurements where the noise bandwidth is much greater than the RBW, such as in the measurement of power spectraldensity. For example, some companies specify IS-95 CDMA ACPR measurements that are spot-frequency power spectral density spec...
