4. EEE340Lecture 424 2. Waveforms voltage May be obtained from the Lattice diagram. Near-end Far-end Middle point Numerical values Near end: V(0,t) Different

5. EEE340Lecture 425 As the steady state voltage is where

6. EEE340Lecture 426 Hence, This is the circuit result.

7. EEE340Lecture 427 b) Far-end

8. EEE340Lecture 428 Middle Point Note that at the near, far and middle point all share the same voltage.
