More often than not a question pops up in our forum about speaker impedance and the result of connecting multiple speakers to a single amplifier. Thus we have prepared this introductory tutorial to ...

Loudspeaker Impedance is often stated as a single rating in ohms. This is done for the sake of simplicity, as few ,if any, real loudspeakers present a constant load to their amplifiers. Typically, the ...

The unity-gain op amp (operational amplifier) buffer circuit is routinely used to transform high-impedance inputs into low-impedance outputs. ADC (analog-to-digital converter) voltage references are ...

When used with other blocks and modules, a new approach to modeling operational-amplifier output impedance behavior can provide a more realistic overall behavioral model. Simulating the behavior ...

The video covers the basic impedance-only Smith chart, as well as a full-color Smith chart which indicates both impedance and admittance. This video is the introduction to a planned series on ...
