Ok I am having a problem understanding the math in the network analysis section I do not understand it at all. I was able to understand everything (well with a lot of double reading) until I got to this section. I am very new to electronics and this is my first post ever. If anyone could help brake these mathematical schemes down for me I would greatly appreciate it. Also I would love to find someone in the Lake Havasu AZ. area that works with this stuff if anyone could get me in contact with someone in the local area I would appreciate it. Our local college does not cover microelectronics so I cant turn there and even if they did I am already in full time on computer programming.
