 Danish said: (Apr 23, 2017) conversion time= (2^n - 1)/fclk. So, 7.5 micro seconds is the correct answer. D is correct.

 Parashu.Kn said: (Nov 4, 2017) correct answer is, CONVERSION TIME = 2^4/2*10^6. = 8 MICRO SECOND. CONVERSION RATE = 1/8*10^-6. = 125 killo/SEC. So answer is D.

 Ajay said: (Mar 17, 2018) Conversion time= frequecy/2^(n-1); where n= number of bits =>ct=2X10^6/2^3:since n=4; =>ct=125 X 10^3.

 Tanaya said: (Oct 14, 2019) Conversion rate = clock rate/2^n, where n=number of bits. Which implies, conversion rate= 2 X (10^6)/2^4. i.e (10^6)/8 => 125 X 10^3 seconds. Therefore, Answer = B.
