Detection methods [for SETI]

Ways to identify computational origins include looking for repeatability in apparently random signals and comparing with output from large collections of possible simple programs. At a practical level, the one-dimensional character of data from radio signals makes it difficult for us to apply our visual systems—which remain our most powerful general-purpose analysis tools.
