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 ...

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 ...

This online guide includes a wealth of practical tips for choosing suitable equipment, setting up measurements, running tests, and interpreting the measurement results. To investigate the stability of ...

(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 ...
