Abstract
An embodiment of a method for control of signal level is disclosed. In such an embodiment, a number for a pre-cursor set, a number for a cursor set, and a number for a post-cursor set are set corresponding to a weighted contribution of a pre-cursor symbol, a weighted contribution of a cursor symbol, and a weighted contribution of a post-cursor symbol, respectively, for the signal level. A number associated with a high-impedance set is determined. The number associated with the high-impedance set is determined by subtracting the number for the pre-cursor set, the number for the cursor set, and the number for the post-cursor set from a total available amount of units. The high-impedance set provides no weighted contribution to the signal level. Data is transmitted using the signal level set responsive to the pre-cursor set, the cursor set, and the post-cursor set.
