Derive the transfer function of the circuit in Fig. P2.93 (for an ideal op amp) and show that it can be written in the formwhere and Assuming that the circuit is designed such that 2 1, find approximate expressions for the transfer function in the following frequency regions:(a) 1(b) 1 2(c) 2Use these approximations to sketch a Bode plot for the magnitude response. Observe that the circuit performs as an amplifier whose gain rolls off at the low-frequency end in the manner of a high-pass STC network, and at the highfrequency end in the manner of a low-pass STC network. Design the circuit to provide a gain of 40 dB in the middle frequency range, a low-frequency 3-dB point at 100 Hz, a high-frequency 3-dB point at 100 kHz, and an input resistance (at
