BASIC STRATEGY USED IN ANALYSIS
THE MODELS THAT WILL BE DEVELOPED HAVE
NICE MATHEMATICAL PROPERTIES.
IN PARTICULAR, THEY WILL BE LINEAR WHICH
MEANS THAT THEY SATISFY THE PRINCIPLE OF
Homogeneit y & Additivity
Here we introduce the basic concepts and laws that are
fundamental to circuit analysis.
OHMS LAW - DEFINES THE SIMPLEST PASSIVE ELEMENT: THE
KIRCHHOFFS LAWS - THE FUNDAMENTAL CIRCUIT CONSERVATION
ADDITIONAL ANALYSIS TECHNIQUES
The property has two equivalent definitions.
We show an application of homogeneity.
We discuss some implications of the superposition property in
Complex Numbers in MATLAB:
There are 2 ways to define a complex number in MATLAB:
1) z = x+i*y
2) z = r*exp(i*theta)
To determine r from z = x+i*y:
r = abs(z)
To determine theta from z = x+i*y:
theta = angle(z)
To determine the real
