Question

Which statement best supports the use of digital transmission of data over analog?

A) Analog signals are an exact copy of the data.
B) Digital signals can be amplified just as well as analog signals.
C) Analog signals have been used for a much longer time to transmit data.
D) Because of the nature of digital signals are immune to noise and imperfections.

Answer 1

The correct answer would be option D, Because of the nature of digital signals are immune to noise and imperfections.

Step-by-step explanation:

Analog signals are the signals which changes over time. Analog signals consists of continuous waves, where as a digital signal is a discrete wave which transfers data in the form of 0 and 1, which is called the binary form.

Analog signals are subjected to deterioration while transmitting data from one point to another, whereas digital signals are immune to noise and imperfections. Digital signals have noise immunity and less susceptibility to interference caused by noise during the transmission of data.
