When getting from point A to point B is all you’re worried about, simple step inputs usually suffice. But when your machine’s movement between points needs smooth elegance, then a complex, controlled ...

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 ...

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 ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) AC parameters which describe the amplifier's performance over frequency can appear very ...
