This course continues the studies about semiconductor electronic devices such as BJTs, JFETs and operational amplifiers and their application in more complex circuit applications. The course introduces concepts related with power amplifiers and their frequency response, filtering, oscillating circuits, rectification in power supplies, radio-frequency principles, including amplitude modulation (AM), frequency modulation (FM) techniques, analog television and digital television principles. Finally, the course includes a general background about digital computer architecture applied in modern computer designs.
