D 2.92 Figure P2.92 shows a circuit that performs the high-pass, single-time-constant function. Such a circuit is known as a first-order high-pass active filter. Derive the transfer function and show that the high-frequency gain is (−R2/R1) and the 3-dB frequency ω0 = 1/CR1. Design the circuit to obtain a high-frequency input resistance of 1 k, a high-frequency gain of 40 dB, and a 3-dB frequency of 2 kHz. At what frequency does the magnitude of the transfer function reduce to unity?
