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 ...

This course provides a continuation of ETEC.2130. Topics include sinusoidal waveforms, phasors, impedance and network elements. Mesh and nodal analysis of AC circuits; series and parallel circuits, ...

Once upon a time, you studied the electric circuit theory where you learned many techniques to analyze electric circuits.Two famous and analogous techniques are the nodal voltage analysis, and the ...

Invented more than 15,000 years ago, knots represent one of the earliest technological breakthroughs at the dawn of human history that kick-started the subsequent rise of human civilisation. Even ...
