high voltage op amp using UA741

The op-amp UA741 is wired to operate in three frequency ranges- high, medium and low. The circuit is designed such that the circuit produces +/-20 dB boost or attenuation for 50Hz,1KHz and 10Khz by varying POT’s R2. The maximum amplification for any of these bands at maximum supply voltage is 20dB.
