AUDIO FREQUENCY DIGITAL NOISE GENERATOR
When you need to test an audio circuit with broadband noise, this circuit works great. It uses just three inexpensive C-MOS ICs that generate a series of output pulses whose widths vary
randomly. I included a level control pot.

Make noise with a PIC : 08/07/03 EDN-Design Ideas / (added 10/03) Building a stable noise generator for
audio-frequency purposes requires only a few components. The circuit in Figure 1 relies on linear-feedback shift registers and some simple software. An eight-pin Microchip (www.microchip.com)
PIC12C508 controller (IC2) with a short program generates pseudorandom noise at its output pin, GP0....
Single IC forms pseudorandom noise source: 03/21/02 EDN Design Ideas / (added 1/05) Trying to find a
single IC noise source can be frustrating. National Semiconductor once made such a noise source for audio applications, but it's now hard to find. This situation leaves the designer with
several choices, most of which involve using several ICs. You can take the analog approach of using a lot of gain to amplify diode-avalanche noise, or you can design a linear-feedback-shi...
