3. Definition Of Electronics
The field of
electronics is a branch
of physics and
electrical engineering
that deals
with the
emission,
behavior and
effects of
electrons
using
electronic
devices.
Electronics uses
active devices to
control electron flow
by amplification and
rectification, which
distinguishes it
from classical
electrical
engineering,
which only uses
passive effects
such as
resistance,
capacitance
and
inductance to
control
electric
current flow.
Electronics has
hugely
influenced the
development
of modern
society.

4. Electronic devices and components
An electronic component is any physical entity in an electronic
system used to affect the electrons or their associated fields in a
manner consistent with the intended function of the electronic
system. Components are generally intended to be connected together,
usually by being soldered to a printed circuit board (PCB), to create
an electronic circuit with a particular function (for example an
amplifier, radio receiver, or oscillator). Components may be
packaged singly, or in more complex groups as integrated circuits.
Some common electronic components are capacitors, inductors,
resistors, diodes, transistors, etc. Components are often categorized
as active (e.g. transistors and thyristors) or passive (e.g. resistors,
diodes, inductors and capacitors).

5. Types of circuits
Circuits and components can be divided
into two groups: analog and digital. A
particular device may consist of circuitry
that has one or the other or a mix of the two
types. An important electronic technique in
both analog and digital electronics involves
the use of feedback. Among many other
things this allows very linear amplifiers to
be made with high gain, and digital circuits
such as registers, computers and oscillators

6. 1.Analog circuits
Most analog
electronic
appliances, such as
radio receivers, are
constructed from
combinations of a
few types of basic
circuits. Analog
circuits use a
continuous range
of voltage or
current as opposed
to discrete levels as
in digital circuits.
The number of
different analog
circuits so far
devised is huge,
especially because a
'circuit' can be
defined as anything
from a single
component, to
systems containing
thousands of
components.
Analog circuits are
sometimes called
linear circuits
although many non-
linear effects are used
in analog circuits such
as mixers,
modulators, etc. Good
examples of analog
circuits include
vacuum tube and
transistor amplifiers,
operational amplifiers
and oscillators.
One rarely finds
modern circuits that
are entirely analog,
These days analog
circuitry may use
digital or even
microprocessor
techniques to improve
performance. This
type of circuit is
usually called "mixed
signal" rather than
analog or digital.
Mathematical
methods are
integral to the
study of
electronics. To
become proficient
in electronics it is
also necessary to
become proficient
in the mathematics
of circuit analysis.
Circuit analysis is the
study of methods of
solving generally
linear systems for
unknown variables
such as the voltage at
a certain node or the
current through a
certain branch of a
network. A common
analytical tool for this
is the SPICE circuit
simulator.

7. 2.Digital circuits
• Digital circuits are electric circuits based on a number of discrete voltage levels. Digital
circuits are the most common physical representation of Boolean algebra and are the basis of
all digital computers. To most engineers, the terms "digital circuit", "digital system" and
"logic" are interchangeable in the context of digital circuits. Most digital circuits use a binary
system with two voltage levels labelled "0" and "1". Often logic "0" will be a lower voltage
and referred to as "Low" while logic "1" is referred to as "High". However, some systems use
the reverse definition ("0" is "High") or are current based. Quite often the logic designer may
reverse these definitions from one circuit to the next as they see fit to facilitate their design.
The definition of the levels as "0" or "1" is arbitrary.
• Ternary (with three states) logic has been studied, and some prototype computers made.
• Computers, electronic clocks, and programmable logic controllers (used to control industrial
processes) are constructed of digital circuits. Digital signal processors are another example.

8. Electronics theory
Mathematical methods are
integral to the study of
electronics. To become
proficient in electronics it is
also necessary to become
proficient in the mathematics
of circuit analysis.
Circuit analysis is the study of
methods of solving generally linear
systems for unknown variables such
as the voltage at a certain node or the
current through a certain branch of a
network. A common analytical tool
for this is the SPICE circuit simulator.
Also important to
electronics is the study
and understanding of
electromagnetic field
theory.

9. Electronics industry
The electronics industry consists of various sectors. The
central driving force behind the entire electronics industry
is the semiconductor industry sector, which has annual
sales of over $481 billion as of 2018.The largest industry
sector is e-commerce, which generated over $29 trillion in
2017.The most widely manufactured electronic device is
the metal-oxide-semiconductor field-effect transistor
(MOSFET), with an estimated 13 sextillion MOSFETs
having been manufactured between 1960 and 2018.In the
1960s, U.S. manufacturers were unable to compete with
Japanese companies such as Sony and Hitachi who could
produce high-quality goods at lower prices. By the 1980s,
however, U.S. manufacturers became the world leaders in
semiconductor development and assembly.

10. Advantages and Disadvantages of Electronic Communication
Advantages
1.Speedy transmission: It requires only a few seconds to communicate through electronic media because it
supports quick transmission.
2. Wide coverage: World has become a global village and communication around the globe requires a second

3. Low cost: Electronic communication saves time and money. For example, Text SMS is cheaper than the
traditional letter.
4. Exchange of feedback: Electronic communication allows the instant exchange of feedback. So communication
becomes perfect using electronic media.
5. Managing global operation: Due to the advancement of electronic media, business managers can easily
control operation across the globe. Video or teleconferencing e-mail and mobile communication are helping
managers in this regard.

11. Disadvantages
1. The volume of data: The volume of telecommunication information is increasing at such a fast
rate that business people are unable to absorb it within the relevant time limit.
2. The cost of development: Electronic communication requires huge investment for
infrastructural development. Frequent change in technology also demands further investment.
3. Legal status: Data or information, if faxed, may be distorted and will cause zero value in the eye
of law.

12. Applications of electronics
• The electronics is used in communication and entertainment applications such as telephony and
telegraphy, optical communication, wireless communication, television communication etc.

13. How does e communication affect people's lives?
Electronic communication hinders
kids social and verbal skills as well.
For example, sometimes things are
read and misinterpreted the wrong
way because you can't physically hear
the tone of voice or see the manner
they are expressing their thoughts in.

14. The Importance of Electronic Communication in Workplace
Innovations in electronic communications
technology spurred the Information Age, a time
period featuring fluid, almost instantaneous
information transmission. The digital world offers
interfaces such as email, instant messaging and
chat rooms that help with simultaneous
transference of information to a large number of
people. For many organizations, electronic
communication has become a necessity for
participation in modern commerce. Electronic
commerce has opened up many opportunities
because it allows large-scale global collaboration.

15. Conclusion
In conclusion, wireless communications globally is something that people
can expect as technology advances. Wireless communications has a lot of
benefits and can make the world a lot more efficient. It does have concerns
though as with every other new advancement that is made in todays world.
The issues with security regarding access to a persons personal
information or the negative impact that it may seem to have on society are
a few things that are holding back the progress that wireless technology
could be making. With more research and experiments conducted, the
problems associated with wireless communications can be reduced and
make it a more significant part of the world. Wireless technology will be
very important in the near future where the need for wires connecting
individual devices seems to be coming to an end.
