What will happen if the input analog voltage (Va) is greater than a digital-ramp ADC's full-scale (Vax) value?
A) The counter will repetitively count up from zero to maximum producing a continuously repetitive staircase waveform at Vax.
B) The counter will count up to its maximum value causing Vax to reach its full-scale output. All operations will then cease until Vax decreases below Vax.
C) The comparator will detect that Va is larger than the Vax full-scale output and all operations will cease until Va decreases below Vax full-scale.
D) The comparator will detect that Va is beyond the range of Vax and will keep the ADC's output at zero until Va is decreased below Vax full-scale.
