A coding technique (1300) encodes each pulse of a pulse stream as a pair of pulses (1316). The scheme is used with gates (1302) that produce an output only when pulses are separated by a specified interval. Using multiple such gates, a signal with symbols defined by different pulses spacings will select only the symbol matching a particular gate configuration. This can be used to route the symbols. The basic technique can be expanded for use with multiple layers of gates.
