QUESTION 1 Anna the Audiophile has asked for your help to build an amplifier and filter to take small signals from her hifi system and amplify them so that she can drive her new subwoofer. The hifi system produces AC signals at varying frequencies with 250mVrms maximum magnitude. Her subwoofer requires the signals to be 20 Vrms maximum magnitude. The signals that Anna is interested in are below 200 Hz. She would like the filter to attenuate signals at frequencies above 200 Hz. Hifi system 250 mV rms Vin Amplifier and Filter Va 1 2 SWI Subwoofer C₁ = 1000 uF Vout twt 4Ω Speaker (a) Design the amplifier and filter circuit to meet Anna's requirements. The circuit must produce the required gain, and also attenuate the signals above 200 Hz. Show calculations for the selection of components where practical. Show a circuit diagram for the complete amplifier and filter circuit.
