Reduced wiring requirements with signal slope manipulation

A method includes manipulating at least one electric signal received from one or more electronic components to provide a slope substantially proportional to a discrete integer data value of n discrete integer data values, n being a positive integer greater than or equal to 3, said discrete integer data value represented by using one of n distinct slopes, said one of n distinct slopes to be transmitted utilizing a particular reference voltage of n predetermined reference voltages. The method further includes transmitting data as the particular reference voltage of the n predetermined reference voltages to at least one electronic component utilizing slope manipulation.
