Let Google translate it from german to your language.
Does the difference come from voltage vs. power spectrum?
Yes, integrating the power spectrum of white noise produces flicker
noise

Yes. When you integrate you get a f^-1 slope in voltage
Hi all!
I friend of mine wants to construct an experiment for students for
studying random walk noise.
What is the best good available transistor or other parts? All parts he
tested where just to good.
Thank you!

Flicker noise is not the same as random walk noise, the spectra differ.
Using an AC coupled generator (eg a sound card) filters out the low
frequency content.
Zeners and transistors (biased at low current) can be used to generate
flicker noise directly at least for low frequencies where it
