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 ...

Analog behavioral modelling (ABM) allows designers to implement their own devices when only first order effects are necessary. In-line equation syntax differs from editor to editor. IsSpice4 uses the ...

When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...
