Midterm examination scores: histogram

Assignment (

Review chapter 3, 4, and 5. Understand the concept of equivalent circuits. The dc equivalent circuit should have been taught in ENEE302. We will review it and add the capacitive component. Then, the equivalent circuits will replace the transistors in various circuits. You will see that this is a powerful, convenient method to hand calculate the frequency performance, including the input impedance, the output impedance, the voltage gain, the current gain, and the cut-off frequency.

Assignment (

Review this handout,
copied from the 4^{th} edition of Sedra and
Smith, on the poles and zeros. Refer to the Appendix E for a similar discussion
