YouTube Lectures on Electronics I
These are recorded lectures from the Electronics I class (ECE 3235) taught at Vanderbilt University. These lectures were given in front of a student audience, and consequently contain some interactions and questions from them.
These lectures tend to follow the presentation of topics in "Microelectronics Circuits" by Sedra & Smith, which is one of the standard undergraduate texts for introductory electronics. However, they can still be used with other textbooks with some rearrangement of topics.
