How Do DACs Work? - The Learning Circuit

In this lesson of The Learning Circuit, Karen discusses digital to analog converters, or DACs. The world around us is analog, but the technology we use is often digital. So we need a way to make our technology communicate with the real world. Sensing the world around us generates analog signals. These can be converted to digital signals that our technology can understand by using ADCs. To get signals back out of our technology, sometimes we need to convert those digital signals back to analog. For this we use DACs. In this video, Karen explains how they work and why we need them: https://bit.ly/3rP6rsm Engage with the element14 presents team on the element14 Community - suggest builds, find project files and behind the scenes video: http://bit.ly/2MFMG0v Visit the element14 Community for more great activities and free hardware: Tech spotlights: http://bit.ly/2KLz0TS Roadtest and Reviews: http://bit.ly/2KH4fj3 Project14: http://bit.ly/2wPnajx
