What does the equivalent circuit have to do with the impedance measurement? Does it really matter if we choose a series or parallel representation of a real life passive component? To obtain the most ...

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 ...

Author’s note: This article shows how to derive circuit gain equations via a signal flow graph. With practice you may be able to write a gain equation by locating signal paths and loops in the ...
