Consider a differentiator circuit such as that shown in Fig. 2.14 a), on page 79 of the Text, having a 5 ms time constant. For what rate of change of input signal is the output +1 V? An input signal begins to rise from zero volts at r = 0 at the rate of 1 V/ms, rcachcs a value of 20 V, then falls at the same rate to zero volts. Sketch and label the resulting output waveform over an interval of 50 ms.
