A system and method is provided for making highly accurate data propagation delay measurements in a serializerdeserializer integrated circuit. The source signature, after processing with the same initial processing steps used on the data, is used to design a phase control filter that shapes the seismic data to have a minimum phase spectrum or whatever other phase spectrum the subsequent processing algorithms may assume. The type of the content includes internal content to be reproduced in the mobile terminal, and external content from outside the mobile terminal.
