It is unlikely that a power operational amplifier will always be employed to drive a purely resistive load. For if that were the case, stability would rarely become a problem. On the other hand, a ...

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 ...

Using my Multisim SPICE tool to analyze an oscillator, I ran into a little bit of simulation trouble. My circuit was a simple Colpitts oscillator and the simulation showed that it would indeed ...

Closed-loop control systems are sometimes shipped from the factory with resonances and other operational difficulties that aren't supposed to be part of the package and are not well understood.

Bode plots – or frequency response graphs – are found in just about every piece of literature for high-end audio equipment. It’s a simple idea, graphing frequency over amplitude, but making one of ...

For the development of dynamic systems in electrical engineering, control engineering, and even mechatronics, the steady-state response at the output of the system to harmonic excitation (sinusoidal ...
