Electronics Engineering Articles and Tutorials

Electronics engineering is the electrical engineering discipline. It deals with the fabrication, design, utilization, and operation of non-linear and active electronic components. The discipline can be further divided into embedded systems, analog electronics, digital electronics, and power electronics. Electric Shocks provides plenty of electronics engineering articles.

Electronics Engineering Uses:

Electronic Engineering has changed the lifestyle of mankind in the last few decades. After the invention of the solid-state device, the vacuum tubes are replaced by transistors and the size of equipment becomes compact.

Electronics can be divided into analog and digital electronics. Digital electronics uses Boolean Functions (AND, OR, NOT, XOR, XNOR). Where analog electronics uses diodes and transistors in rectifiers and oscillator circuits.

Subfields:

Subfields of Electronics engineering are signal processing, telecommunication engineering, aviation engineering, electromagnetic, instrumentation, computer, and VLSI engineering.

Professional Organizations

Professional bodies for electrical and electronics standardization are the Institue of Electrical and Electronics Engineers (IEEE) and the Institution of Engineering and Technology (IET).

Electronic Engineer Jobs

Electronics Engineers are in demand nowadays. As the world is digitizing and everything is transforming, Electronics engineers can help us more.
