Line 28:

* the line-coded signal (the ''[[baseband]] signal'') undergoes further [[pulse shaping]] (to reduce its frequency bandwidth) and then [[modulation|modulated]] (to shift its frequency) to create an ''[[RF signal]]'' that can be sent through free space.

* the line-coded signal can be used to turn on and off a light source in [[free-space optical communication]], most commonly used in an infrared [[remote control]].

* the line-coded signal cannotcan be printed on paper to create a [[bar code]].

* the line-coded signal can be converted to magnetized spots on a [[hard drive]] or [[tape drive]].

* the line-coded signal can be converted to pits on an [[optical disc]].
