Abstract
An encode-decoder system for generating highly accurate, coinciding synchronizing signals at each of plural separated locations; for example, a system generating start signals for a seismic data acquisition system. The system transmits psuedo random code data over selected communication link to a respective position decoder which samples the incoming code and compares it with a standard code. If there can be established a predetermined number of successive code matches, an output start signal is enabled when the code match count first peaks and then decreases.
