WHY WE NEED TO STUDY ELECTRONICS AND
COMMUNICATION ENGINEERING (EC)?
Before
going to know about the electronics and communication engineering, let us
imagine the world without electronics. Can we? We can’t right. The devices and
components which we use in our daily life-like TV’s, computers, mobiles,
cameras, home appliances, and gadgets are related to these electronics.
What
Are The Things That The EC Deals With?
Electronics
And Communication Engineering deals with all the electronic devices like circuits and communication equipment like transmitter, receiver, integrated circuits. It is an electrical engineering discipline that utilizes non-linear and active electrical components like semiconductor devices, mainly transistors, and diodes. It also deals with basic electronics like analog and digital transmission, microprocessors, satellite communication, microwave engineering, antenna, and wave progression.
It aims to give the knowledge and skills to the students on the basic concepts and theories that will equip them in their professional work involving analysis, systems implementation, operation, production, and maintenance of the various applications in this electronics field of engineering.
The main intension of studying EC is to provide easy and effective communication. It uses the scientific knowledge of the behaviour and effects of electrons to develop devices, systems, or equipment that uses electricity as part of its driving force. Also, it has some basic concepts on electrical machines and more on integrated circuits and communication systems.
Now you people may think
about, what are the specializations in EC? Here you are
VLSI DESIGNING:
Very-large-scale integration (VLSI) is the process of creating an
integrated circuit (IC) by combining millions of MOS transistors in a single
chip. VLSI began in the 1970s when MOS integrated circuit chips were widely
adopted, enabling complex semiconductor and technology development. The
microprocessor and memory chips are VLSI devices. Before the invention of VLSI
technology, most ICs had a limited set of functions they could do.
DIGITAL
SIGNAL PROCESSING:
Digital
signal processing (DSP) is the use of digital processing, such as by computers
or more specialized digital signal processors, to do a lot of signal processing
operations. The digital signals processed in this manner as a sequence of
numbers that represent samples of a continuous variable in a domain such as
time, space, or frequency. In digital electronics, a digital signal appears as
a pulse train, which is typically generated by the switching of a transistor.
COMMUNICATION
ENGINEERING:
Communication
engineering includes modes of communication such as radio, internet, satellite
and broadband, and wireless telephone services. The role of a communication
engineer is to research, design, develop communication equipment. This
information can be transferred in two ways. One is digital and the other is
analog communication.
EMBEDDED
SYSTEM:
An EMBEDDED
SYSTEM is a computer system with a dedicated function within a larger
mechanical or electrical system, often with real-time computing constraints,
which means our PC or smart phone are not embedded systems but the Bluetooth
module or graphic card in our PC are of embedded systems. It can also be
defined as “A microprocessor-based system does not look like a computer “.
MICROWAVE
ENGINEERING:
Microwave
defined as the part of the electromagnetic spectrum with large infrared waves
and short radio waves. Microwave engineering pertains to the study and design
of microwave circuits, components, and systems. Microwave devices and systems
can be divided into information transmission types and power types. The uses of
information-transmission devices and systems include radio communication,
television, radar, radio navigation, radio control, etc. microwave devices and
systems are powerful tools for scientific research in such fields as
radio-frequency spectroscopy, solid-state physics, nuclear physics, and radio
astronomy.
WIRELESS
COMMUNICATION SYSTEM:
It is the
electromagnetic transfer of information between two or more points that are not
connected by an electrical conductor. The most common wireless technologies use
radio waves. Wireless communication is a broad term that incorporates all the
processes and forms of connecting and communicating between two or more devices
using a wireless signal through wireless communication technologies and devices.
MICROELECTRONICS:
Microelectronics
is a subfield of electronics. As the name suggests, it relates to the study and
manufacture of very small electronic designs and components. In
Microelectronics, we can learn about processor design, chip design, or IC
fabrication. It has been rapidly evolving as the most in-demand field of
electronics because of the ever-increasing demand for inexpensive and
lightweight equipment.
Wondering
why there are only some listed above?
Well, there
are hundreds of domains and sub-domains in EC and we will be here reading all
day long if we choose to. I think these are the main domains among the
remaining ones and there are several sub-domains to these, which we are going
to cover slowly and briefly very soon. Till then, keep learning and keep
finding your best carrier option.
