If
Graph [1] is no Crosstalk and no RFI
Graph [2] is no Crosstalk but with RFI
Then
Graph [3] with Crosstalk and RFI in theory should look something like the blue line.
Please note the graph is NOT to scale, nor have I analysed individual tones, but just based on tones 432+ are affected more than tone 414. Its a very quick and crude projection.
