How many bits should be employed to obtain a resolution

1. The problem statement, all variables and given/known data

An A/D converter is to operate with a full-scale voltage of 10V. How many bits should be employed to obtain a resolution of 0.01%?





2. Relevant equations

Resolution = Full Scale voltage / (2^N - 1)





3. The attempt at a solution



.01% * 10 V = .01/100 * 10 V = .001



.001 = 10 V / (2^N - 1)



N = 13.2879 = 14 bits



I am just learning this stuff, but 14 bits seems high to me. I believe the mistake is in the Resolution. I am just assuming they me the resolution is .01% of the full scale voltage, this seems wrong to me.



Thanks for any help!
