What is electronics and function of it?????
What
is electronics?
The
brunch of engineering which deals with conduction of electron through a field named gas, vacuum and semiconductor is
called the Electronics. An Electronics device
is that conduct electron through it .
Such
as Transistor, Diode, TRIAC, DIAC etc.
Duties
of Electronics Device: The electronics device performs the following functions.
1.
Rectification
2.
Amplification
3.
Control
4.
Generation
5.
Conversion
of Light into Electricity
6.
Conversion
of Electricity into light.
7.
Rectification:
The
conversion of AC into DC is called the rectification. The efficiency of this device is so much high compared to
the others.
Amplification:
The
process of raising strength of a weak signal is called the amplification such
as weak signal as a radio signal and receiver take this signal by a antenna and
raise it into the strengthen signal as a amplification, after that we can here
it as audio signal with a clear sound.
Control:
Electronic
device that is used for handling the electrical device such as motor is called
the control. The motor is controlled by a electronic device.
Generation:
Electronic
device can convert DC power into AC power of any frequency. The process is
called the oscillation and the device is used for oscillation is called the
oscillator.
Conversion
of light into electricity:
We use internet in our daily life and the
signal transfer through a media is called optical cable. Optical cable is made with
optics and its can handle only light signal. So a electronic device is used for
conversion of light into electrical signal at output terminal or at a receiving
end.
Conversion
of electricity into light:
At
the sending end of optical communicaltion, an electrical signal is converted into an light signal by a
electronic device.
