1. A method for addressing a plurality of devices on a network comprising:
- defining a plurality of addresses, where each address is a unique sequence of two or more signals, where each signal in a respective sequence has a frequency, and at least one signal has a predetermined duration;
or the sequence has a predetermined, time-specific pause between at least two adjacent signals;
or at least one signal has a predetermined duration and the sequence has a predetermined, time-specific pause between at least two adjacent signals; and
assigning one of the plurality of addresses to each device;
where the combination of pause, duration, or pause and duration, with frequency distinguishes one address from another.

Abstract
A method and device for decoding a sequence of signals in which information is derived, in part, from a duration of (a) one of the signals and/or (b) an inter-signal pause between two of the signals. The method and device may also be used to decode a signal to form decoded information, derived, in part, from a duration of the signal.
