Explanation: The number of comparator required almost doubles for each added bit. For example – 2 -bit ADC requires three comparators, 3 -bit ADC needs seven comparators and a 4 -bit ADC requires fifteen comparators. 8. Drawback of counter type A/D converter
A. Counter clears automatically
B. More complex
C. High conversion time
D. Low speed
