A rectangular voltage pulse which begins at t = 0, is 2 seconds wide and has a height of 0.5 V drives an RC lowpass filter in which R = 10 k? and C = 100 ?F.

a) Graph the voltage across the capacitor versus time.

(b) Change the pulse duration to 0.2 s and the pulse height to 5 V and repeat.

(c) Change the pulse duration to 2 ms and the pulse height to 500 V and repeat.

(d) Change the pulse duration to 2 ms and the pulse height to 500 kV and repeat. Based on these results what do you think would happen if you let the input voltage be a unit impulse?
