Re: [sdiy] Various colors of noise.

2026-03-03 by rburnett@richieburnett.co.uk

If the ZIP attachment makes it through it contains five examples of 
"white noise" created with different amplitude distributions:

1. Gaussian distribution
2. Uniform (all amplitudes equally likely)
3. Triangular distribution
4. Two discrete levels (Digital PRBS)
5. Three discrete levels (Two digital sources added together)

See if you can tell the difference by listening!
