Embedded SystemsName: Signal Conditioning In the DC voltmeter lab, you designed an interface circuit which restricted the voltage applied to the ADC to a range between 0 and 5 volts. The circuit appears below. Design a new circuit which restricts a +/- 12 V input signal to a range between 0 and 3.3 V. Show all calculations.
