The analog input channel voltage range for a PIC16 Microcontroller is limited to the positive range 0-Vref. Many situations require a digitized mapping from bipolar analog signals to unipolar signals. A simple resistive network has been designed to translate a bipolar voltage range of ±10V to a unipolar range of 0-6.6 V, assuming Vref is +6.6 V. A reasonable resistor combination is: a. None of them b. 2.212, 2.70, and 5 Kohms c. 2.212, 2.70, and 2.70 Kohms d. 1.122, 1.70, and 3.30 Kohms
