ENHANCING SINGLE-ENDED LOOP TESTING SIGNALS

摘要

Methods, systems, and devices are described for wired communication. In one aspect, a method relates to a scheme to filter and enhance a time domain reflectometry (TDR) plot with pre-processing such that the plot shows impairments clearly and reduces spurious peaks. The method includes receiving one or more reflected signals in response to a transmitted test signal. The method also includes determining a time domain reflectometry (TDR) signal based at least in part on frequency response data associated with the received one or more reflected signals. Additionally, the method includes applying a de-emphasis windowing function to the TDR signal.

1. A method for measuring impairments in a transmission line, the method comprising:
receiving one or more reflected signals in response to a transmitted test signal; determining a time domain reflectometry (TDR) signal based at least in part on frequency response data associated with the received one or more reflected signals; and applying a de-emphasis windowing function to the TDR signal.
