Day 17 04/28/2015 Second order Circuit

Class Note

2nd order deviation

========================================================================

For this lab, the RLC circuit we build that we using the analog discovery we supplied to build a function into the circuit. the second-order circuit we have discover that the circuit is under damped by α < ω  .

In this prelab we determine the circuit is under damped by α < ω and apply to the function i(t)=e^-αt(B1coswt+B2sinwt)

These graph is the Vout after we supplied 2V step function at the frequency 100 Hz

we record two peaks timing and amplitude then

We then solved the experimental Wd by 2pi/delta t and figure out a result which is about 96 % error

In this lab on solving second order circuit. Second order circuit contain both capacitor and inductors. They are know as second order circuits because their response is described by the differential equation by taking second deviation. 

To be able to understand second order circuit we know:

α > ω means over damped

α > ω means critically damped

α < ω means under damped
