Make a DAC with a microcontroller's PWM timer - 09/05/02 EDN Design Idea Many embedded-microcontroller applications require generation of
analog signals. An integrated or stand-alone DAC fills the role. However, you can often use PWM signals for
generating the required analog signals. You can use PWM sig. . . [by Mike Mitchell, Texas Instruments Inc]
Make
noise with a PIC - 08/07/03 EDN Design Idea 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.
