Question

Q2)

A unipolar 14 bit ADC measures 0 – 8 volts full scale.

a. What is the minimum resolvable voltage (or voltage resolution)? [Hint: resolution decrease as you increase the volts full scale]

b. What is the percent quantization error? [Hint: percent quantization error for unipolar 10 bit ADC, 1 V full scale is: (resolution/max voltage) x100% or (975μV/1V) x100% = 0.0975%]

c. What is the percent quantization error if a 1 volt max signal is input? [Hint: same resolution as part a, smaller max voltage; error should increase]

Q3)

A bipolar 8 bit ADC measures 0 – 4 volts full scale.

a. What is the minimum resolvable voltage?

b. What is the percent quantization error?

c. What is the percent quantization error if a 1 volt max signal is input?
