question 24 of 33
an audio signal was copied, and the copy is identical to the original. which is most likely to have been the type of signal that was copied?
a. digital
b. analog
c. infrared
d. radio

Explanation:

Digital signals are represented by discrete values (usually binary - 0s and 1s). They can be accurately copied without degradation as long as the copying process is error - free. Analog signals are continuous and are more prone to noise and degradation during copying. Infrared and radio are types of transmission media or signal carriers, not the fundamental nature of the signal like digital or analog. Since the copy is identical to the original, it is most likely a digital signal.

Answer:

A. Digital
