Basic Electronics From Scratch

electronics circuit analysis and design from the ground up

What you'll learn
Basic principles of electronics
Requirements
A familiarity with basic algebra is a boon.
Description
Basic Electronics From Scratch picks up from the short, free Electronics Fundamentals course, and continues, guiding the student through the unique mathematics used to analyze and design reactive circuits comprising resistance coupled with capacitors and inductors, and their use in filters and resonant circuits. Logarithmic graphs are key tools in filter design, and the principles behind this compression method are explained in detail. Transformer operation is described, and the course turns to the wide world of active components: bipolar and FET transistors, amplifier biasing and coupling, feedback, specialized diodes, photo-responsive devices, and digital switches. Power-handling semiconductors are introduced before rounding out the course with an introduction to op amps, the universal electronics building block. Like the Fundamentals prelude course, Basic Electronics uses straightforward diagrams and audio instruction to impart a clear, easily-absorbed understanding.

Comprehensive assignments cover key subject areas, expanding on the lecture material. The student will find many challenging, and challenge solidifies understanding.

Electronics has been described as the real-world manifestation of algebra. A true grounding requires the use of math, and a working understanding of the technology of electronics needs only the most basic, first-year, grasp of algebra – e.g., ratios and equation manipulation. If you understand that x= 1/y+z is the same as y=1/(x–z), then you will have no problem.

Who this course is for:
Anybody curious about how electronics works, no previous technical education necessary.
