A digital signal composed of a pulse of positive voltage represents a(n) ____.
A) 0
B) 1
C) 4
D) 8

Question

Quizplus · Accepted Answer

A pulse of positive voltage is commonly used to represent a 1 in digital electronics, while a zero is typically represented by a no pulse or a pulse of negative voltage. Therefore, the best choice is B, which represents a 1. Choices C and D are not relevant options because digital signals typically use a binary system, meaning there are only two possible values (0 or 1), and 4 or 8 are not part of that binary system. Choice A is also not the best choice because, as mentioned earlier, a pulse of positive voltage usually represents a 1.
