APPARATUS AND METHOD FOR COMPENSATING DIGITAL INPUT DELAYS IN AN INTELLIGENT ELECTRONIC DEVICE
摘要
An apparatus and method for compensating digital input delay in an intelligent electronic device is provided. A method is provided which provides for accurate SER data recording while facilitating the reduction of processing burden on the IED and optimization of system performance during the processing of SER data flow. An apparatus is further provided which generally includes a time delay element coupled to a sequential events recorder for compensating for delay in communication of a data signal such that the sequential events recorder records a compensated time for a select event based on the clock and the time delay. An apparatus is provided which includes an edge detection element for detecting either a rising or falling edge from the data signal.
