Devices, systems, methods, and other embodiments associated with generating a moving average are described. In one embodiment, a method calculates, using at least an accumulator, an average value of M sequential data values is calculated, where M is an integer. The M sequential data values are delayed before passing a delay output. The method detects a data value with an error in the M sequential data values that are delayed and controls the accumulator to correct the average value of the M sequential data values as a function of the error.
