Ludwig EE3113_L1 2 EE 3113: Lecture 1 Importance of RF circuit design wireless communications (explosive growth of cell phones) global positioning systems (GPS) computer engineering (bus systems, CPU, peripherals exceeding 1 GHz) At high frequency all digital circuits become distributed analog systems Dr. R. Carley, IC_Mechanics Why this course??? lumped circuit representation no longer applies! EE3113_L1 3 What do we mean by going from lumped to distributed theory?
