I'm still working on developing a good understanding the use of transistors – and especially biasing for the application of amplification. As a result, I came across this great video on YouTube.
There are additional videos too – in theory a Lecture 12 that goes on to more biasing methods and their use as amplfiers. But I'm still to look and find that.
