6.5.5 SDC and RTS display using a Pink Noise Source
The spectrum of a pink noise signal is essentially at, in a Constant-Q analysis. That is caused by the pink noise or 1/f noise having a power spectral density
(energy per frequency interval) that is inversely proportional to the frequency of the signal.
Due to the stochastic nature of the noise, it will have signal at many dierent levels, hence the spread of the SDC curves. The curves appear ‘noise’ in the low end,
due to the ‘imperfect’ statistics of the relatively short test signal.
