Use op amp and filter circuits to build a telephone amplifier from 300 to 4k Hz with again of 50 (or -50). Check points: 1) -3dB frequencies at 300 Hz and 4 kHz. 2) voltage gain of 50 in mid-band.
Please help to solve the problem above. I have got a start and think that to design this I have to cascade high pass and low pass to form band pass to get desired frequencies and then cascade it to a op-amp(ua741) to get gain. I kind of know the equations but still please help me solve the problem and let me know if my start is a correct start or not.
