Turn Your Computer's Sound Card into a Scope

摘要

I've been using an oscilloscope for almost 50 years. It's my go-to measurement instrument in every electronics project I work on, helping me debug and fine-tune hardware and software projects. In this article, I'll show how you can get started with a simple-to-use scope you probably already have. Best of all, it's free! When you graduate from this simple scope, you can purchase a more powerful scope using the exact same user interface.
