High Quality White Noise Gen
in [Design]
|
From: Jim Slone on 31 May 2010 08:23 What are the best options for high quality audio white noise generation? I have been using generic diodes and reversed biased transistors. Then someone mentioned there are special parts available with better characteristics. Can anyone please give me a pointer? Jim Slone

See AoE for details. For audio, it doesn't matter much. A 10-volt zener biased at a few mA is fine. John
