a) Sketch and explain the v-i characteristic of an ideal diode. (3 marks) b) Sketch and explain the v-i characteristic of a physical diode (equation, parameters, and curve). (3 marks) c) Using four diodes, explain the operation of a full- wave rectifier (circuit and waveforms). (4 marks) d) In Fig. 1 find the condition in which the ideal diode D1 is conducting. e) Find and carefully sketch the output voltage V circuit with respect to time. out (3 marks) of this (4 marks) f) Calculate the maximum and the minimum values of the output voltage.
