Electronics Engineering or rather Electronics and Communication Engineering is the branch of science and technology and is basically a part of Electrical Engineering discipline. It has a broad area of study including the study of linear and nonlinear electronic devices, semiconductor devices, study of electromagnetic spectrum and devices utilizing this spectrum for communication purpose. With the age of miniaturisation, the discipline also includes the study of Very Large Scale Integration or VLSI circuits.
With its dependency on an interdisciplinary branch on Computer Science, the Electronics branch also deals with areas like the architecture of computer systems, networking, Artificial Intelligence and Data Structure Concepts. This is the reason why Electronics and Communication Engineers can easily migrate and adapt themselves over different work sectors including the IT and core industries.
Some of the fields of study under the Electronics Engineering branch are –
Embedded Systems – It is the field of study related to the devices serving specific application such as everyday consumer electronics or bigger systems like flight control system. A microcontroller is the heart of any embedded system application. It also includes the study of Real-Time Operating System which is different from the conventional Operating System used in computers and laptops.
VLSI (Very Large Scale Integration) systems – The ever-reducing size of the electronic devices is made possible through this field. It is the field of engineering where the system is created on a single chip. Not to stop here the technology aims at still reducing the size of the Integrated Circuits by reducing the MOS’s channel length. This is an ever-demanding industry and VLSI engineers are always sought after in this industry.
RF Communication – This includes the study of wireless communication using radio waves and making use of the Electromagnetic spectrum. This type of communication is used in mobile phones, Internet of Things using Cloud technology, and short- and long-range radio communication. With the advancements made in 5G and Cloud technology, this branch of engineering is also highly preferred.
Digital Engineering – We are well aware of the advantages of Digital Communication over its analog counterparts. This is the reason and hence no doubt that the Digital market has completely taken over the analog market.
Systems Engineering – The field deals with the design of any electronic system, be it a radio receiver, a mobile phone or it may be an object consisting of several smaller items. Good design adds to the system’s efficiency and its productivity and hence Systems Design is an integral part of the Electronics Engineering branch.
Control System Engineering – The modern advancements in luxury cars like the cruise control system or flight propulsion control system are all apart of Control Systems Engineering.
Telecommunication Engineering – It deals with the transmission of information across the channel or wired media such as optical cable, coaxial fibre or free space. It also includes the study of various modulation techniques like amplitude and frequency modulation. After determining the transmission characteristics of the system, the telecommunication engineers design the transmitters and receivers needed for the system required.
Instrumentation Engineering – This field deals with the study of designing devices which can measure physical quantities such as temperature, pressure or flow. The devices used for measuring these physical quantities are called instruments. It also requires knowledge of physics besides electromagnetic concepts. These concepts are often applied in making and calibrating various sensors which are part of a larger system like automobiles or industrial machines.
There are many other sub-branches of Electronics Engineering discipline like Analog Circuit designing, Robotics, ASIC designing, Programmable logic engineering, etc. which are also sought-after fields.
