Question

Select the correct statement(s) regarding the difference between analog and digital signals. a. analog signals are comprised of an infinite number of amplitudes and time slices b. digital signals are only represented by discrete values of "0s" and "1s", and therefore can never convey analog information c. digital signals are more accurate than analog signals; this is why digital music sounds much better d. analog networks easily fit into the OSI Reference Model

Answer 1

Analog signals use a continuous range of values to represent information, while digital ones use discrete, binary values. Digital signals can, however represent analog information. The perceived 'better' quality of digital music is subjective, and the OSI reference model refers to digital networks.

Step-by-step explanation:

In the comparison between analog and digital signals, statement a. is correct because analog signals are indeed comprised of an infinite number of amplitudes and time slices. This allows them to represent continuous signals precisely.

Statement b. is partially true. Digital signals are represented by discrete values of '0s' and '1s',which simplifies transmission and reduces noise. However, digital technology can emulate analog information with a high level of precision, hence our digital audio and video technologies.

Statement c. is not universally true. The perceived quality of digital music being 'better' is subjective and can depend on various factors such as the sampling rate, audio hardware, and encoding.

Statement d. is incorrect, as the OSI Reference Model is digital network model. Analog networks operate differently.
