... KHz. These data points at the different harmonics represent the ratio of the output noise to the input noise. Depending on the application needs one can use this illustration to help determine the capacitive needs for the filter (see Figure 2). The plot is given in Log scale. AN1988 Rev 1, 10/2004 1).
