This very simple digital noise source provides pure white noise over the full audio spectrum. With the additional filtering shown, it can also produce pink noise and red noise. Digital noise sources have a bad reputation, mainly due to the infamous MM5837 chips that appeared in the Sequential Prophet 5. This chip allegedly makes a noise like a broken recording of a steam train. It uses a 17-bit LFSR at a rate which is somewhere between 24KHz and 56KHz. The datasheet doesn't commit itself to offering a `typical' rate between these extremes. Assuming ...
