1 ECED3201: Introduction to Electronics Fall 2009 Dalhousie University, Department of Electrical and computer Engineering Assignments #4 Problem 1 - [5 points]: For the circuit in Fig.1, assume ideal diode. The initial condition across C is zero. Let v in (t) be a 4-volt peak sinusoid. v in v O D 1 + _ C + _ t 0 t f Fig.1 a. Sketch the output waveforms v O (t) between the time interval of t 0 and t f and indicate the functionality of the circuit. Problem 2 (5 pts) For the circuit in Fig.2, assume ideal diode. The initial condition across C is zero. Let v I (t) be a 10-volt square wave signal. a. Sketch the output v o for the input v I shown. Explain how you obtain these waveforms. Hint: find v o while considering RC>T but not so much (e.g. RC 5T). You may perform approximate analysis for several cycles and show the final voltage levels of the
