(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Show that the least significant bit (LSB) corresponds to a change in the analog signal of V/(2^N-1).

2. Relevant equations

D=b_0 * 2^0 +b_1 * 2^1 + ... + b_(N-1) * 2^(N-1), where b_0 is the LSB, and b_(N-1) is the MSB.

3. The attempt at a solution

I have absolutely have no idea what they are asking or how to solve it. I tried using the fact that 0 means logic 0 (off) and V means logic 1 (on). I think that the change in analog signal that they are talking about means that from when the bit number changes from the LSB to the next bit number, the change in amplitude of the analog signal. I tried that fact that 2^0 equals 1, and plugged that into the given expression, but that still did not make any sense. Does "correspond" mean that the LSB is proportional, or equal to the change in analog signal?

How can I solve this problem?
