Unformatted text preview: University of California, San Diego Department of Electrical and Computer Engineering ECE65, Spring 2010 Lab 3, Diode wave-form shaping circuits In these experiments we examine diode circuits that modify the input wave-form. In these cases (and in many future experiments) you are asked to print out scope traces of input and output voltages of the circuit. You should follow this procedure: 1) Attach Scope channel 1 to v i , Scope Channel 2 to v o , and have both traces be triggered by channel 1. 2) Move the two traces such that the zero voltage value for both channels are in the middle of the display. 3) Expand the time selection so that only 2 to 4 periods of the wave-form are shown. 4) Adjust the volt per division knob such that the signal is as large as possible ( i.e., fills the display). Ensure that both channels have the same volt per division setting. 5) Printout the trace. In this manner v o and v i can be directly compared....
