1 ECE2280 Homework #1 Spring 2010 1. Given V g =10mV, find V o . Find the Thevenin equivalent between terminals a-b. (Note: v 1 Vg) 2. Sketch the following waveforms. Identify the dc component of the waveform and the ac component of the waveform. a. Vs=5cos( 20 t) V b. Vs=7V +7cos(2 π t) V c. Vs=8V ± 1V 3. Explain in your own words the procedural steps for plotting Bode Plots. (Note: I would prepare this question for use during an exam) Use the following equation for problem 4 and 5: ) 50 )( 10 ( ) 5 . ( 2000 ) ( + + + = s s s s s H 4. (a) Plug in values of ω from 0.1 to 10 5 rad/sec to obtain the magnitude and phase plots. (b) Sketch the Bode plots using a straight-line approximation (procedures described in class) 5. Using the equation from problem 4 above. (a) Use Matlab to obtain the Bode Plots. (b) Compare the 4(a), 4(b) and 5(a). What differences do you see? 6. Sketch the Bode plots for the equation below using a straight-line approximation (procedures
