Design an audio amplifier that amplifies signals from 2 kHz to 10 kHz. Your approach should be to use a cascade connection of two first-order passive circuits separated by a non-inverting OP AMP. 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 2 kHz, fCH ¼ 10 kHz, B ¼

8 kHz. Passband gain +40 dB. Use OrCAD to validate your results. Even though problems 12–25 and 12–26 share similar constructs one cannot achieve the desired specifications in 12–26. What is the reason for the problem?
