In the following circuit , the comparator output in log: "I" if V1 > V2 and is logic "0" otherwise. The D/A conversion is done as per the relations VDAC = 2n-2 Volts, where b3 (MSB), b2, b1 and b0 (LSB) are the counter outputs. The counter starts from the clear state
The stable reading of the LED display is
Answer : Option D
Explanation :
Using the given VDAC relation we can get tc
Thus stable reading of LED is 6.5 x 2 = 13.
