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 ...

Electrical engineers will recognize the Bode plot as a plot of the frequency response of a system. It displays the frequency on the x-axis and the phase (in degrees) or magnitude (in dB) on the y-axis ...

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 ...
