Design an interface circuit that connects a stereo IPOD headphone jack output to a sound system as depicted in Fig. 1. The sound system has an input resistance of 100 k and is designed to deliver 100 W of power to the right and left channels of the system when its input receives a 10 V peak-to-peak signal with no DC component. The goal is to maximize the sound power delivered by the speakers while operating from a specific power supply level (as will be determined shortly). The amplifier must pass audio signals in the frequency range of 100 Hz to 20 kHz with no greater than 3 dB of attenuation. In addition, the output signal from your amplifier at full level should not significantly alter the shape of the input signal. The IPOD headphone jack is designed to have a 100 output resistance with a maximum peak-to-peak output of 500 mV.
Also, your job is to design the DC power supply for the amplifier as shown in Fig. 2. The IPOD is connected to a separate internal power supply; it is important that these two systems share the same ground.
