Making sound with digital logic usually calls for a Digital to Analog converter. Building one can be very simple, and the sound quality out of an R-2R Ladder is actually pretty good. In the last ...

Audio and low-frequency circuit systems often require a signal source with a pure spectrum. DDS (direct-digital-synthesis) devices often perform the signal generation by using these specialized ...

This file type includes high resolution graphics and schematics when applicable. Laboratory data often appears as Gaussian curves, and today's laboratory data-acquisition software is designed to ...

Analog-to-digital converters (ADCs) are used in a wide range of electronic devices. However, most of the low-cost microcontrollers do not include an ADC peripheral. This design idea provides a way to ...
