Analog Circuit Analysis can be difficult. Consider the circuit below. It includes a Series Resonant Circuit. With Ideal Impedances, the Series Impedance ...

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 ...

Also examined are two types of LPFs in the context of attenuated voltage-reference noise: simple passive RC LPFs and active-based signal - flow - graph (SFG) LPFs.
