PDU - Bits

The abstracts is in $.25 $.25 are adapted to signals accepted as encoding

The concrete band is additionally amenable for how bifold advice is adapted to a concrete band signal. For example, if the cable uses chestnut as a carriage medium, the concrete band defines how bifold 1’s and 0’s are adapted into an electrical arresting by application altered voltage levels. If the cable uses fiber, the concrete band defines how 1’s and 0’s are represented application an LED or laser with altered ablaze frequencies
