Chapter 9

Frequency Domain Circuit Analysis

Izzat Darwazeh and Luis Moura

9.1 Introduction

In this chapter, we present the main electrical analysis techniques for time-varying signals. We start by discussing sinusoidal alternating current (AC) signals and circuits. Phasor analysis is presented and it is shown that this greatly simplifies this analysis since it allows the introduction of the generalized impedance. The generalized impedance allows us to analyze AC circuits using all the circuit techniques and methods for DC circuits discussed previously. In section 9.3, we extend the phasor analysis technique to analyze circuits driven by nonsinusoidal signals. This is done by first discussing the Fourier series, which presents periodic signals as ...
