4. (30 points) Find the differentiator output voltage at each time listed below under the impulse input as shown in the figure. Assume the voltage across C is 0 at t = 0, and the input pulse source starts a 4.5v jump at t = 0. You need to give the math formula for Vout for the period te [0, 10 ms] and t [10 ms, 20 ms]. (a) 0 ms, (b) 2 ms, (c) 5 ms, (d) 10 ms, (e) 10 ms, (f) 12 ms, (g) 15 ms, (h) 20 ms; (f) Draw the output voltage curve in your figure and show the maximum voltages for 4 periods. 4.5V 0- 110 ms 10 ms 10 ms] C 1F th R 1.0 kf2 Vout -0 5.
