It may come as a surprise to some that a control loop’s Bode plot does not always depict the loop stability and that the output impedance measurement, obtained non-invasively, always does. Challengers ...

In 1938 Hendrik Wade Bode, who worked at Bell Labs, published his asymptotic assessment of phase margin and gain margin, bearing his name [2]. The Bode plot is recognized for its simplicity and the ...

Electrochemical impedance spectroscopy (EIS) is used in this procedure to test the impedance in a commercial battery after connecting it two ways. An analysis of the differences in the obtained values ...
