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 passive circuits separated by a non-inverting OPAMP. The source has a 50-V series resistor and the output of the filter feeds a 10-kV audio transducer.

Design a bandpass circuit with the following specifications all

 5%: fCL ¼ 20 Hz, fCH ¼ 20 kHz, B ¼ 19980 Hz. Passband gain +40 dB. Use OrCAD to validate your results.
