Question

Quizplus · Accepted Answer

A modem must be used to convert an analog signal to a digital one in order to transmit data over a typical phone line. A modem essentially modulates and demodulates the signal to make it compatible with the digital equipment on both ends of the transmission. Option A (fiber optic switch) and option D (tunnel) are not relevant to this specific scenario, and while DSL (option B) does involve digital transmission, it is not directly related to the question of converting analog signals to digital for transmission over a phone line.
