Technician A says that a digital voltage signal is continuously variable within a certain voltage range. Technician B says an amplification circuit in the input conditioning chip will amplify a low voltage signal. Who is correct?
A) A only
B) B only
C) both A and B
D) neither A nor B

Question

Quizplus · Accepted Answer

Technician B is correct because an amplification circuit in the input conditioning chip is indeed used to amplify low voltage signals, making them more detectable or usable by the system. Technician A is incorrect because a digital voltage signal is not continuously variable within a certain voltage range; instead, it switches between discrete values, typically representing binary 0s and 1s.
