If you are looking forward to start your career as an electronics engineer or are just aspired by some relative,friend or neighbor who’s progressing in this filed already,you might just first like to know what this filed of engineering is all about and what scope you’ll find once you’re fully qualified.

To define in the simplest words Electronics Engineering is that branch of engineering  in  which the behavior and effects of electrons is studied and used to develop components, devices, systems  that uses electricity as part of its driving force.It  involves the design and testing of electronic circuits that may be using one or more of the components such as resistors,inductors,capacitors,transistors,diodes or triodes to achieve a particular functionality.It is a  broad engineering field that encompasses many sub-fields some of which are enlisted and briefly described below in terms which may be helpful for you to decide where you wish to get your hands into .

• Control and Maintenance Engineer is required almost in every industry. This is because controlling a system, device or machine is essential to produce good quality and quantity results. If ,for instance,  a machine is not controlled properly to produce a desired amount of output,it can ruin the overall production as well as cause huge losses for the repair or replacement of that machine.Together this machine requires regular maintenance(such as oiling or replacement of parts on regular intervals) to ensure excellent,cost effective production in the allocated time .

Control engineers design control systems using the feedback generated from its output of the system to control its input. For instance, in an electric iron,the temperature is continuously monitored and fed back to the thermostat. If the temperature is too high,further heating will not take palce until the temperature drops back again below the desired temperature for ironing.

• Instrumentation Engineer: deals with the design and calibration of devices and instruments required  to measure physical quantities such as temperature,pressure,humidity,flow,potential difference,speed  etc. These are vital factors which require strict control in any industry ,hence Instrumentation engineers always remain in a good demand in the market.

The design of such instruments requires a comprehensive knowledge of physics and physical laws. For example, to measure pressure often pressure sensors like quartz crystals may be used which work on the piezoelectric effect. Likewise,thermocouples use the Peltier Seekback effect to measure the difference in temperature between two points. Instrumentation engineering may be seen as the counterpart of control engineering.

• Telecommunications Engineer deals with the transmission of information across a channel or medium(wired or wireless). In free space(wireless medium or air interface),information requires to be modulated before being sent to the receiver. The choice of modulation affects the cost and performance of a system and these two factors must be balanced carefully by the engineer.

After determining the transmission characteristics, telecommunication engineers design the appropriate transmitters and receivers required for such a system.  Sometimes they may be assembled together to form a two-way communication device called the transceiver. A key design consideration here is the consumption of power which is related to the signal strength which should be sufficient enough to avoid the signal from being corrupted by noise. Noise is a highly undesired feature in signal transmission but it cannot be completely eliminated.

• Computer Engineer:is indulged in  design of computers and computer systems. They may further be divided as Software Engineers or Hardware Engineers.

Software Engineers deal with the programming and use of computer languages to design a software that meet a company’s requirement. They maybe required to design a software to enhance the security of a company or continuously develop new programs on whichit is easier for the employees to work on,hence producing maximum output in minimum time. They can get well paid also develop some  new computer games as the computer gaming industry is on a boost these days.

Hardware Engineers, on the other hand, have most to do with the design of physical components and gadgets used on ,with or as a substitute to the computers. They may design  computerized parts of other appliances too. They are involved with both  the mechanical as well as electrical components (which includes electronic components too)of computers and computer systems, such as  data cabling, switching,routing,processing units, memory and storage,processing units, storage of data and memory, etc.  This is a rather interesting job and hardware engineers are paid well for it.
