What is the minimum number of bits required to sample a signal with a range of 1 volt at a resolution of 1 millivolt?
4 bits
6 bits
8 bits
10 bits✓Bonne réponse
Explication
A 1 volt range resolved in 1 millivolt steps needs 1000 distinct levels. An n-bit converter provides 2ⁿ levels, and 2⁹ = 512 is not enough while 2¹⁰ = 1024 is, so 10 bits is the minimum.
