Question

Design an audio amplifier (the circuit of which is given below), using a single LM741A op-amp, with thefollowing characteristics: gain=20 dB, input resistor R1= 10K, -3dB point = 20 Hz

(cutoff freqeuncy). Usethe non-inverting configuration, and roll off the gain at low frequencies with an input coupling capacitor sizedto meet the low-frequency gain specification and to reduce the effects of input offset voltage. Use properdesign to minimize the effects of input bias current on output offset. Assume that the signal source has zerooutput impedance Zout = 0. Determine the bandwidth of your audio amplifier design and calculate the roll-off(reduction) from the mid-frequency gain (in dB) at the highest audio frequency of 20 kHz. Determine thehighest input sinusoidal signal peak amplitude Vm, in the audio frequency range of 20 Hz to 20 kHz, that maybe amplified by your design without distortion. Use the attached specification sheets for the LM741 to obtainthe op-amp characteristics data you need for the design; select the worst-case values for the characteristicsneeded in your design. Show all the equation development in your report.
