Extracted text: 2. b) (i) Derive an expression for the differentiator using op-amp. (ii) Design a circuit to perform differentiation of an input signal that varies in frequency from 20HZ to about 2 KHz. (iii) If a sine wave of 0.5 V peak at 2 KHz is applied to the differentiator of part (ii), draw the output waveform.
