ABSTRACT:
The invention can be used to extract information in a Synchronous Digital Hierarchy (SDH) transmission system and relates to the extraction of information from a PCM data stream. It is desirable to provide a Dual Filtering Method for a System having dual data rate justification in a simple manner using minimum components. To obtain a relatively simple circuitry a single controlled oscillator source is used to time the data output stream.
