The study of inverse nodal problems in Sturm-Liouville theory is dedicated to the reconstruction of underlying potential functions and boundary conditions by utilising the nodal (zero-crossing) data ...

Analog Circuit Analysis can be difficult. Consider the circuit below. It includes a Series Resonant Circuit. With Ideal Impedances, the Series Impedance is equal to zero at the resonant frequency. A ...

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 ...
