A 12-bit bipolar DAC has a 10.00-V reference.
a. What output voltage results from digital inputs of 4A6H, 02BH, and D5DH?
b. An output of 4.740 V is needed. What digital input would come closest to this value? By what percentage is the actual output different?
c. Suppose the output picks up a high-frequency noise of 50 mV rms. How many output bits are obscured by this noise?
