Abstract: The embodiments herein describe a modified TDECQ that can measure correlated noise (i.e., non-random noise). Instead of generating a single histogram for a TDECQ test pattern (e.g., which can include thousands of symbols), the embodiments herein generate a respective histogram for each of the symbols of the test pattern (e.g., thousands of histograms). These individual histograms can be processed to determine an error probability for each symbol, which can provide valuable insight into correlated errors.
