triangular waveform voltage (shown below to the right) is applied to the following circuit input terminals. The circuit's value of C is 200 nano-farad and the value of R is 60 kilo-ohm. The output voltage is measured with a high impedance Analog-to-Digital converter. Recall that such a passive element circuit is a linear-time invariant system which can be solved with superposition principles: a) Determine eout at time = 1.5 milli-second. b) Determine the difference between e out and ein at 2.25 milli-second. c) Determine the time when ein / 2 = eout d) Determine eout at time = 8 milli-seconds
