Abstract
A transient signal detector for monitoring a signal line and generating a control signal which indicates when the magnitude of a differential signal on the line exceeds either a positive or negative threshold value. The threshold value is defined by a single current, thereby allowing for a single, simple adjustment of such threshold in both the positive and negative directions.
