The device that converts digital signals to analogue signals at the start of long-distance transmissions is
-
- peripheral
- modem
- telephone
- antenna
Correct Option: B
A modem takes the digital signal from the computer and converts it to "analog". It does this by both creating an analog sine wave and then "MODulating" it. Since the result still represents digital data, it could also be called a digital signal instead of analog.
