Course Details for A.Y. 2014/2015

Course Objectives

The course is aimed to the study and comprehension of some analog electronic blocks. It is the second course on the same argument (first part, course name: Elettronica I). Students should learn basic analog blocks as operational amplifiers and current-conveyors, positive and negative feedback, square wave generators, etc.
