What is electronics?
Electronics is a branch of physics and electrical engineering, in which we talk
about small things like semiconductors. The word electronics is derived from
electron mechanic, which means the study of the behavior of electrons and the
application of different conditions.
In this field we study that how the circuit works, and how we can
design the circuit by ourselves, all this we understand through electronics, in
this we also learn to do some calculations for the circuit etc.
Electronics teaches us how we can make our lives easier, and in
electronics we talk about how to create a circuit to make meaningful work out
of electricity, you know that electronics devices are very important to us. And
we need it more from time to time, whereas now any work is very difficult
without the use of electronics, because electronics can easily do anything for
us.
We generate electricity through batteries, generators, or solar
panels. The electricity generated by electrical system, but electronics can
convert electricity into a particular work or task, and it limits the flow of
electrons, that is, it controls the current on specific amount.The some different branches of electronics is following
- Digital electronics
- Analogue electronics
- Micro electronics
- circuit design
- Opto electronics
- Integrated circuit
- Semiconductor device
- Power electronics
1- Digital electronics
This is a branch of electronics which study about digital signals
or devices, digital electronics system used digital signals instead of analog
signals, the digital electronics common represented by Boolean algebra and this
is basic of all digital circuit.
The digital electronics work by only two fixed values which is
"1" and "0" the digital electronic perform any work at this
values such as communication or store information, also digital electronics can
perform mathematics by using only '1" and "0", it is called
Boolean math or Boolean logic.
The digital signals faster than analog signals, means it can take
more information in per second, the digital circuit is easy to make and this is
very cheap than analog circuit,
Many things in our house using digital signals, such as
Television, Mobile, laptop, washing machines, also computer, the computer is
very complex example, because a simple computer has four basic functions like,
input output, memory, control unit and also mathematical unit.
Uses: - Television, Computer, Mobile, Hard disk, USB,
Flash memory, etc.
2- Analogue
electronics
Analog is the branch of electronics it concerned about
continuously variable signals, it mostly used in audio and radio appliance it
has low uses other equipment.
The first signals are taken from the analog sensor, then
converting to digital signals for storage and processing.
The analog circuit distribute into two types,
1- Active analog circuit
2- passive analog circuit· An
analog circuit uses a source of electrical power to achieve a designer's goals.
· Passive
circuits do not use any external power.
Uses: - it not use is micro processer, chips it used in
Radio Signal, Audio Signal, etc.
3- Micro
electronics
It is a branch of electronics related to micro components such as
transistors, capacitors, diodes, resistors, inductors, conductors and
insulators, etc. The Microcircuits and microchips are designed in this field.
Now demand is increasing for smaller and less expensive equipment,
for this, microelectronics is expanding, and more research is being done in
this field in many areas.
It is the only branch that deals with microelectronics components
and circuits, and many equipment or device produce by using micro electronics
method.
4- Circuit Design
Circuit design is the branch of electronics that deals with
circuit designing and analysis. In this section we talk about the process of
any circuit and how to design any circuit.
Circuit design is the process of physical form, that is, gives
physical shape to any electronics circuit. Circuit designing is main starting
step for each project designing, and it requires create diagrammatic. The
schematic diagram show that how pins of components on a printed circuit board
which logically connected together.
The circuit designer is responsible of circuit designing, that
makes the electrical system, and designer's other responsibilities include
making various types of circuit boards and making signal processing filters.
5- Opto Electronics
This branch deals with combine use electronics and light, opto
electronics is study of electronics device that detect and control to the
source of light, the opto electronics equipment are electronics appliances it
operate on light and electrical current.
An optoelectronic device can convert energy into light, it
produces light through electrical energy, it can also detect light and transmit
light into electrical signals.
This branch is lastly widening technology, this includes the use
of electronic devices for light sourcing detection and control, the opto
electronics light involve invisible forms of radiation, such as X-rays,
ultraviolet, and infrared.
Its components made by solid crystalline material, its heavy than
insulator and lighter than conductor
Uses:- Blue Laser, Telecommunication Laser, Photo Diode
and also Solar Cells.
6- Integrated
circuit
This branch belongs to the Integrated Circuit IC, also known as
microelectronics or microchips. Chips are a combination of many components of
electronics such as diodes, capacitors, resistors. We do a lot of components
combine on a very small and thin plate, meaning a thin plate has a whole
circuit.
Jack Keby, the man who created integrated circuits, and possibly
microchips, on September 12, 1958, was a TI engineer. Microchips develop the
electronics industry and help to make cell phones and laptops, computers, and more.
Uses:- Micro processor and Micro Controllers.
7- Semiconductor
device
The Semiconductor device is a electronics equipment which use
semiconductor components like silicone, gallium arsenide and germanium and as
well as organic functions, the semiconductor devices have replaced vacuum tubes
in most equipment.
The components of a semiconductor are between the conductor and
the insulator which help in making electronics components like diodes,
transistors, integrated circuit ICs etc. Another advantage is that the price is
very low.
Example:- Transistor, MOSFET,
Diode, etc.
8- Power
electronics
This branch deals solid state electronics is used to control and
convert electrical power. The power electronics devices used for electronic
switches that control electrical power.Uses:- DC to DC converter or AC to DC it used more in Mobiles or
laptop.
In this field we study that how the circuit works, and how we can design the circuit by ourselves, all this we understand through electronics, in this we also learn to do some calculations for the circuit etc.
