1. A data communication method including:
- transceiving successive first and second synchronization signals defining endpoints of a frame, the transceiving including modulating time length between a portion of the first synchronization signal and a portion of the second synchronization signal to represent a digital signal; and
transceiving at least one first data pulse during the frame, a relative position in the frame of the first data pulse representing a first analog signal.

Abstract
A system and method involve transceiving successive first and second synchronization signals defining endpoints of a frame. A digital signal is transceived by a modulating time interval between portions of the first and second synchronization signals. A first data pulse is transceived during the frame. A relative position in the frame of the first data pulse represents a first analog signal.
