Answer» The correct CHOICE is (b) The capacitor waveform is a ramp, the output waveform is a pulse, the time period is \(\FRAC{2.C.VCC}{3.I}\) Easy EXPLANATION: If a constant charging current is APPLIED through the capacitor, the output is a pulse, while capacitor voltage is a ramp. Time period of ramp/pulse = TO = 2VCCxC/3I.
