An 8-bit ADC converts analog voltage in the range of 0 to 
to the corresponding digital code as per the conversion characteristics shown in figure. For 
, which of the following digital output, given in hex, is true?
64 H
65 H
66 H
67 H
Explanation:
length of each interval or step size = 19.6 mV
Number of steps for given analog input 
= 101.64
∴ The o/p makes a transition at middle of interval as can be seen from graph.
& 101.64 > 101.5 ∴ output will be hexadecimal value of 102
(102)10 = (66)H
