Hello,

It’s great that you are looking for free online courses from IITs to strengthen your ECE knowledge. Fortunately, India has some excellent platforms that provide IIT-led courses at no cost. The most popular is NPTEL (National Programme on Technology Enhanced Learning), which is a joint initiative of IITs and IISc. Here, you will find free video lectures and course material on subjects like Digital Circuits, Signals & Systems, Microprocessors, Control Systems, VLSI Design, Communication Engineering, and more. You can learn directly from IIT professors at your own pace. Another platform is SWAYAM, which also offers IIT courses, sometimes with free certificates. If you want international exposure, you can also explore edX or Coursera, where IITs have uploaded a few programs.

Thank you, and I wish you great learning ahead.
