Abstract
An encoding and decoding mechanism for communicating digital data where the binary states are represented by a duration of time between transitions of a signal. For instance, the time between zero crossings of a signal are used to represent binary states. These times can be selected so as to avoid ambiguities between the binary state being detected even where the transmission medium is irregular. A typical application is the creation of a LAN in a home using twisted pair telephone lines. The LAN can be made to be transparent and independent of telephone service received over lines shared with the LAN.
