12–37 Design an audio amplifier that amplifies signals from 20 Hz to 20 kHz. Your approach should be to use a cascade connection of two first-order active OP AMP circuits.

The source has a 1-kΩ series resistor, and the output of the filter feeds a 32-Ω audio transducer. Design a bandpass circuit with the following specifications all ± 5%: fCL = 20 Hz, fCH = 20 kHz, B= 19,980 Hz. Passband gain should be adjustable

(use a potentiometer) from 0 dB to + 60 dB. Use Multisim to validate your results.
