1. 2 nd Order: a. What are the important constants when analyzing 2 nd Order Transient? (For 1 st Order Transient we care about τ , DC values) b. What do they mean? Can you make any intuitive guesses as to how they correspond to the transient response? c. Find the constants for the following circuits. Also, analyze the circuit for DC steady-state and right after the DC source turns on. (t=0+, infinity) Now that you have the important constants, how would you find Il, Ic? d. Repeat for below Can you use the same formulas derived from class? Can you gleam insight on how the constants vary versus the ratio of R1, R2? i. Find the Thevenin/Norton equivalent (NOTE: this is an AC representation, so you SHOULD NOT short/open the ind/cap) 2. Transfer Functions and Bode Plots a. Are there additional constants that are useful to have when calculating transfer functions? b. Find the transfer function for problem 4 from Exam 1 – Relate Vc to Vin c. Do the same for 1c, 1d – Relate Vc, Vl, Vr to Vin

Unformatted text preview: d. Plot the ones that look interesting. e. What are the two ways to plot a Bode plot? (Think about how you can represent a quadratic equation, s^2 + s + 1 vs. (s+1)(s+2) yes I know they aren’t equal… ) f. Can you show where the 20 dB per decade comes from? 3. Fun questions – a. Show that the phasor representation of impedances is correct for inductors, capacitors, and resistors b. P6.32 Hambley – (feel free to do the problem first…)Replace the upper left 1k Ω resistor with an Inductor L. Can you do the same analysis? i. Heck, replace all the resistors with inductors and capacitors, can you do the analysis still? c. Consider the following circuit: Would you be able to use phasors to solve for all frequencies? (That is a AC current source) Why or why not? (Hint: consider if the freq were the resonant frequency) d. Repeat for series (Hint #2: Did you do this problem before?) WHY does it fail?...
