EE 201 Lab7 Tian Gu Code:721 Team partner: Tielong Su Chaojun Zhang Introduction     :    In this lab, we mainly focused on two parts: the behavior RLC Circuits’ and the  introduction of diodes. In the first part, we specially see the response of underdamped,  overdamped, and critically damped. And the second part is about the basic i-v characteristics  about diodes. We also knew diodes’ forward bias and reverse bias. Part 1: LRC RLC Voltage Response: According to the waveform, it is underdamped voltage.

Neper Frequency:  =1/2RC = 1/(2*5000*125*10^-9)=800Hz α resonant radian frequency:4000Hz S1 =-  + α  -800+3919.2i S2 =-  - α   -800-3919.2i Because, So, it is underdamped. Neper Frequency:  =1/2RC = 1/(2*200*125*10^-9)=20000Hz α resonant radian frequency::4000Hz S1 =-  + α  =-404.0821
S2 =-  α  =-39595.9180 Because, So, it is overdamped. When it is critically damped,  , 1/2RC = , 1/(2R125*10^-9)* = R=1000 So R=1000  when it is critically damped. PSpice
