  • Red curves: It shows the actual curve of the mask, for given reference bandwidth z, that is:

...


                                   

Mathinline
bodyy = f(x)

...

    (Eq. 72)


  • Blue curves: it shows the curve normalized in a reference bandwidth of 1 MHz, that is:


                                          

Mathinline
body y = f(x) + 10log(1000/z)

...

  (Eq. 73)


The blue curve is aimed to detect potential discontinuities in the definition of transmission mask, and is also the one which is used in actual simulations when integrating the total power of unwanted emissions, in order to overcome possible differences of victim and interferer bandwidths.
