The circuit in the Gray Box below is an interface circuit to an ADC operated from a single-3V supply. It outputs 2Vpp when the input signal is 8Vpp. The output signal is centered at 1.5V

1) Determine the Values of Resistors R1 and R2.
2) Determine the Minimum Acceptable value for the coupling capacitor C if the lowest frequency of the incoming signal is 1.2kHz.
3) What type of op-amp would you choose & why? Explain.
