Methods and apparatus for conditioning low-magnitude events in communications signals

摘要

Methods and apparatus for conditioning low-magnitude events in electrical signals. According to an exemplary method, a low-magnitude event occurring in a signal trajectory of a received electrical signal is analyzed. The low-magnitude event is defined by a data point on a signal trajectory having a magnitude that is less than a predetermined signal magnitude minimum. A correction impulse having a correction magnitude and a correction phase is generated based on the magnitude and phase of data points on the signal trajectory that occur prior to and after the occurrence of the low magnitude event. The correction impulse is combined with the original electrical signal in the temporal vicinity of the low-magnitude event, thereby generating a corrected electrical signal having a more controlled bandwidth.
