Understanding Modern Electronics

Just wanted to pass along that The Great Courses (http://www.thegreatcourses.com/courses/understanding-modern-electronics.html) has added a course titled "Understanding Modern Electronics" that might be of interest to some here. There's several chapters about amplifiers, feedback, etc. They run sales every couple of months of 70% off. I've not bought this title, yet, but have a couple of the mathematics titles.
