Electronic engineering is a discipline where non-linear and active electrical components are utilized to design electronic circuits, devices and systems. Electronic engineering has many subfields including analog electronics, digital electronics, consumer electronics, embedded systems and power electronics. It deals with the implementation of applications, principles and algorithms developed within many related fields.
Electronics is a subfield of electrical engineering. An academic degree with a major in electronics engineering can be obtained through some universities. In the early years, computer engineer was used to refer to a subfield of electronic or information engineers. Today, computer engineering is now considered a subset of Electronics Engineering and computer science.
Electronic engineers design and test circuits that use electromagnetic properties of electrical components such as resistors, capacitors, inductors, diodes and transistors to achieve particular functions. For example, the turner circuit allows the user of a radio to filter out all but a single station.
Electronic engineers design integrated circuits but first constructing circuit schematics that specify the electrical components and describe the interconnections between them. They then convert the schematic to actual layouts. This conversion is done through software but will require human fine-tuning to decrease space and power consumption.
