• Initial and Final Value Theorems

12
COMPLETE TIME RESPONSE

• There is Stored Energy at t 0-
• gtHave Initial Conditions
• Input x(t) for t gt 0 Can be anything
• Output y(t) Complete Time Response
• Use s-domain circuit with fictitious sources in
  models for C L
• Input Lx(t) Tables
• Find Y(s) using s-domain Ckt Analysis
• y(t) L-1 Y(s) PFE Tables, or MAPLE

13
INITIAL CONDITIONS

• Will practice using Laplace Transforms with
  Initial Conditions by doing Activity 39-1
  together and then you do Activity 39-2 on your
  own
• Last look at Laplace Transforms
