Department of Electrical and Computer Engineering ECSE 352 Electromagnetic Waves and Optics 3 Harmonic wave analysis 1.3 Harmonic wave analysis References: Hayt and Buck 11.4, 11.5 AGK2006 1.3-1 Overview Last class we derived equations for voltage and current on lossless transmission lines. I nthi sclass we will be introducing the phasor notation for these quantities. You may already have studied the phasor representation in other courses. This is a very important concept when we are dealing with single frequency or harmonic signals. It is important to eep ear our ind e ifference etween e al keep clear in your mind the difference between the real measurable time independent representation of the voltage and the complex time independent phasor form. ©AGK 2006 ECSE 352 1.3-2 Transmission line classes A.
