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 ...
Power supplies use control-loop circuits to produce constant voltage or current. The transfer function—gain and phase as a function of frequency—provides valuable information about a control loop’s ...
In electronic systems, wires and cables provide intentional circuit paths for power or signal currents to move from a source to a load and then return to the source. These current paths have the ...
