Make noise with a PIC : 08/07/03  EDN-Design Ideas / 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 softw1are. An eight-pin Microchip (www.microchip.com) PIC12C508 controller (IC2) with a short program generates pseudorandom noise at its output pin, GP0....

Memory Game: MeGaM is based upon the early 80s "simple-Simon" game. The opponent (microcontroller) slowly builds up a random LED sequence, which the player has to repeat step-by-step by pressing the corresponding push buttons.

Power Supply Cuts Switching Noise In DDR Memory Systems : 11/11/02 Electronic Design - Ideas for Design / This design idea describes a unique, low-cost power-supply circuit for a double-data-rate (DDR) memory system. Conventional designs for DDR memories consist of a dual buck converter and a voltage reference. In contrast, this design replaces one buck...

Single IC forms pseudorandom noise source: 03/21/2002  EDN - Design Ideas / 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... .
