  • Control loop for data signal baseline correction
    Patent number: 6173019
    Abstract: A closed feedback loop controls the baseline correction of a data signal. Detected signal information about the baseline and positive and negative peaks of the incoming data signal is processed to generate a baseline correction signal which identifies the difference, if any, between the present data signal baseline and that which is desired. This baseline correction signal is summed with the original data signal to bring its baseline into conformance with the desired baseline.
