The resolution of a 0–5 V 6-bit digital-to-analog converter (DAC) is:
I have done 5/64=0.078.but answer is 1.56%.?

6-bits will provide you with 64 steps from 0v to 5v. (Each step is 1.56% of the total range)The resolution of a 0–5 V 6-bit digital-to-analog converter (DAC) is:

Who is 'they' ?I don't have any other info. They may have given wrong answer.
I am solving these question from one of the website.Who is 'they' ?
Well, do you understand where the 1.56% came from?I am solving these question from one of the website.
what www site ?I am solving these question from one of the website.
No. Can you please explain?Well, do you understand where the 1.56% came from?
Both answers are acceptable depending on the circumstance.
If you can share the website you are using, it would be appreciated..No. Can you please explain?
38.16% .Thanks!If you can share the website you are using, it would be appreciated..
Anyway, here are some numbers for you:
6-bits provide 64 possible combinations. ( 0 - 63 )
Now.. even though there are 64 combinations, there are only 63 steps.
So, if you take the reciprocal which is 1 / 63, you find that each step is 1.59% of the whole.
Using the same number, you find that each step of a 5V DAC is 5V / 63 = 0.079V
So at this time you can build a table:
000000 = 0% (0v)
000001 = 1.59% (0.079v)
000010 = 3.18% (0.158v)
000011 = 4.76% (0.238v)
000100 = 6.35% (0.317v)
...
111101 = 96.82% (4.84v)
111110 = 98.41% (4.92v)
111111 = 100% (5v)
Or simply multiply the binary value by the resolution to determine the answer:
So 011000 must be?
