A Few Applications
 Embedded Systems:
• An embedded system is various type of computer
system or computing device that performs a
dedicated function and/or is designed for use
with a specific embedded software application.
• An embedded system is not usable as a
commercially viable substitute for general-
purpose computers or devices.
• Software embedded in Microcontroller Chips.

5. 5
A Few Applications
• Optical Communications :
• Free Space Optics
• Light Fidelity (Li-Fi)
• Visible Light Communications
• Radio over Fiber

6. 6
•
Internet
Global

7. 7
A Few Applications
 Radio Communications :
• Information Converted to electromagnetic
waves of radio frequencies, transmitted
wireless & retrieved by the receiver.
• Signals are electronically processed and
transmitted/reproduced.
• Antennas/Aerials convert electromagnetic
waves into electrical currents and vice versa.
• Includes Mobile Communications, Satellite
Communications, Military & Entertainment
media Communications, Microwave
Communications etc.
• Radio over Fiber.

8. 8
Mobile Communications
• Wireless telecommunications can be
divided into two broad categories: mobile
communications and fixed wireless
communications.
• GSM and CDMA Technologies.
• Smart Phones.
• Long Distance Communications.
• Towards 5G……

9. 9
Satellite Communications
• LEO, MEO and GEO
Satellites.
• A Satellite acts as a
repeater in space.
• Satellite receives signal
from an earth station
(uplink) amplifies and
transmits signal back to
another earth station
(downlink).

Radio Frequency
Identification
• RFID stands for radio frequency
identification. It is an automatic
identification technology whereby digital data
encoded in an RFID tag or “smart label” is
captured by a reader using radio waves.
• RFID is similar to bar/QR code technology
but uses radio waves to capture data from
tags, rather than optically scanning the bar
codes on a label. RFID does not require the
tag or label to be seen to read its stored
data—that's one of the key characteristics of
an RFID system.

11. 11
Radio Frequency
Identification
• Makes life faster, tracks goods and pets.
• Alternative to Bar/QR Codes.
• Active RFID tags have a battery. Passive tags
have no battery, they draw power from the
reader, which sends out electromagnetic waves
that induce a current in the tag's antenna. Semi-
passive tags use a battery to run the chip's
circuitry, but communicate by drawing power from
the reader.

12. 12
Automation
• Timer Control of Home Appliances.
• Industrial Timers and Counters.
• Remote Control of Home Appliances.
• PLC Based Process Control.
• Robot Control.
• Security Systems.
• Machine & Vehicle Control/ Mechatronics.

13. 13
Medical Electronics
• ECG, EEG, EMG, Tomography, Other
Biomedical Equipments.
• Telemedicine related Equipments.

14. 14
Instrumentation
• Art and Science of Measurement of
Parameters.
• Multimeters, Cathode Ray Oscilloscopes,
Function/ Waveform Generators,
Electronics Laboratory and Process
Control Measurement Equipments, Space
and Biomedical Measuring Instruments.

15. 15
Telemetry
• Telemetry is a technology that allows the
remote measurement and reporting of
information of interest to the system
designer or operator. The word is derived
from Greek roots tele = remote, and
metron = measure.
• Wired and Wireless.

16. 16
Back Up and Power
Generation
• Solar Power Generation.
• Power Electronics.
• Inverters and Uninterruptible Power
Supplies (UPS), Power Controllers.

17. 17
Entertainment
Electronics
• Audio Recording & Reproduction.
• Video Recording & Reproduction.
• Broadcasting & Storage.
• Gaming.
• Projection Equipments.
