Figure 3-1 illustrates a graph of the equalizer slope versus equalizer value information
presented in Table 3-1. The amount of cable equals the equalizer value.

When selecting an equalizer, choose the next lower value if the exact value is not available or in
cases where the calculated value makes two choices possible.
Because of errors in cable attenuation, slope in passive devices, and other independent
variables, you may need to change the final value of the equalizer before you install the BLE*/*.
