## AC DC Electronics Learning Track

Courses under AC/DC Electronics are a series of courses that teach you electronics in a practical way. The main characteristic of these courses are the following:

1. They omit all the theory that you are not going to use in your work assuming that you don't want to do anything very complicated in electronics, for example design a full-fledged frequency counter, but you still want to be able to design and build fairly complicated circuits like amplifiers, filters, etc.
2. They will enable you to do all the calculations related to Point 1.
3. They will teach you all the necessary theory related to Point 1.
4. They will teach you all the practical skills, like working with an oscilloscope and other types of test equipment.
5. They will provide you with "Course Exercises" and the related solutions.

In short you could say that these courses teach you the tricks of the trade or teach you the practical parts of electronics in a relatively short amount of time.

These courses are broken down into DC and AC.
