It is not too often that a tool fails me. Most of the time I have made some mistake, so when a Bode Plot failed to predict an unstable system, I came down with a bad case of myopia. I spent so much ...

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 ...

Since the inception of electronic communications, frequency response has been the common measurement unit for most instruments. Even after the introduction of the feedback amplifier, frequency ...
