1. The problem statement, all variables and given/known data Consider the circuit below. If the source υs represents a 12-V, 100-ms-long rectangular pulse that starts at t = 0 and the element values are R1 = 6 kΩ, R2 = 2 kΩ, R3 = 4 kΩ, and C = 15 μF, determine the voltage response υ(t) for t ≥ 0. 2. Relevant equations 3. The attempt at a solution I am trying to use this slide as a platform to start the problem, but I am not sure what the voltage response is vs. natural response, and where I should do the timeshift. Also, I wasn't sure if my thevenin resistance to find the time constant was correct.
