Abstract:
A data recovery system comprising:means for receiving a data signal; means for splitting the data signal into a plurality of data channel signals and a replacement channel signal; means for digitizing the plurality of data channel signals to obtain a plurality of data out signals comprising means for comparing the plurality of data channel signals to a data channel reference energy level to produce a plurality of intermediate data channel signals and means for periodically sampling the plurality of intermediate data channel signals; means for digitizing the replacement channel signal to obtain a replacement signal comprising means for comparing the replacement channel signal to a replacement channel reference energy level to produce an intermediate replacement channel signal and means for periodically sampling the intermediate replacement channel signal; means for comparing at least one of the plurality of data out signals and the replacement signal; means for adjusting the means for digitizing the plurality of data channel signals, the means for adjusting being responsive to a signal generated by the means for comparing at least one of the plurality of the data out signals and the replacement signal.
