Hand Calculation: 1. For different configurations shown in Figure 1, perform approximate hand calculations assuming that the operational amplifier is ideal. In each case sketch the expected output waveform in Table I. Assume that the sine and triangular waves have amplitude of 1V, the square wave varies from 0 to 5V with 50% duty cycle, and frequency of all signals is set to 1kHz. 2. Redesign the integrator circuit so that when the input is sine wave with frequency 1kHz the output voltage will have same amplitude. Use C=0.1μF. 3. Redesign the differentiator circuit so that when the input is sine wave with frequency 1kHz the output voltage will have same amplitude. Use C=0.1μF.
