Statistics Using Analog Techniques

Calculation of Exponentially Mapped Past Statistical Variables Using a True RMS-to-DC Converter

It is often useful to be able to calculate both the average frequency of a signal and the way the average frequency varies with time, that is, the variance of the average. The calculation of the Exponentially Mapped Past (EMP) statistical variables and their use with the electrical signals from the human stomach have appeared in the literature. Read full article
