BASIC ELECTRONICS

An Introduction Course For The Students ofInformation Systems Sciences


2/15

Topics Include:

Introduction to Electrical Engineering

Electric Circuit Theory and Analysis

Semiconductor Devices (Diodes, BJTs and FETs)

Digital Electronics (Boolean Logics,AND,OR etc)


3/15

Introduction to ElectricalEngineering

Electrical engineering deals with the study and application ofelectricity, electronics and electromagnetism

The field now covers a range of sub-disciplines including: power,optoelectronics,

electronics,digital electronics,analog electronics,computer science,artificial intelligence,

control systems,signal processing and telecommunications.


4/15

Distinction Between ElectricalEngineering and Electronic Engineering

Electrical Engineering deals with the problemsassociated with large-scale electrical systemssuch as power transmission and motor control

Electronic engineering deals with the study ofsmall-scale electronic systems includingcomputers and integrated circuits.In other words

Electrical engineers are usually concerned withusing electricity to transmit energy, whileElectronics engineers are concerned with usingelectricity to transmit information.


5/15

Power EngineeringIt deals with the: generation, transmission of electricity

distribution of electricity design of a range of related devices

which includes

transformers,electric generators,electric motors


6/15

It focuses on the modeling of a diverse range ofdynamic systems and the design of controllersthat will cause these systems to behave in thedesired manner.

To implement such controllers electricalengineers may use electrical circuits, digitalsignal processors and microcontrollers

Applications:

flight and propulsion systems of commercialairlinerscruise control in many modern automobilesindustrial automation etc.

Control Engineering

Electronic Engineering

Electronic engineering involves thedesign and testing of electronic circuitsthat use the properties of components

such as resistors, capacitors,

inductors, diodes and transistors to achieve a particularfunctionality.


9/15

Microelectronics

Microelectronics is the miniaturization of theknown technology for a compact andintegrated design of electronic component.

The most common microelectroniccomponents are semiconductor transistors,which has dramatically revolutionized our life

The use of semiconductors, especiallysilicon allowed miniaturization of thecomponents that are having faster, better and

reliable performance.


10/15

Telecommunications Engineering.

Focuses on the transmission of informationacross a channel such as a coaxial cable, opticalfiber or free space.

This is achieved through Modulation where

message signal is encoded on a high frequencycarrier signal suitable for transmission telecommunication engineers design the

transmitters and receivers (Transceivers) A key consideration in the design of transmitters

is their power consumption as this is closelyrelated to their signal strength

If the signal strength of a transmitter is insufficientthe signal's information will be corrupted by noise.


11/15

Instrumentation engineering

Deals with the design of devices to measure physicalquantities such as pressure, flow and temperature

The design of such instrumentation requires a goodunderstanding of physics that often extends beyondelectromagnetic theory.

For example, radar guns use the Doppler Effect tomeasure the speed of oncoming vehicles.

Often instrumentation is not used by itself, but instead asthe sensors of larger electrical systems.

For example, a thermocouple might be used to help ensurea furnace's temperature remains constant. For this reason, instrumentation engineering is often

viewed as the counterpart of control engineering.


12/15

Signal processing

Deals with the analysis and manipulationsof signals

Signals can be either analog or digital

For analog signals, signal processing mayinvolve the amplification and filtering ofaudio signals for audio equipment or themodulation and demodulation of signals

for telecommunications. For digital signals, signal processing may

involve the compression, error detectionand error correction of digitally sampledsignals.


13/15

Computers Engineering

Deals with the design of computers andcomputer systems

This may involve the design of newhardware, or the use of computers tocontrol an industrial plant.


14/15

Artificial Intelligence

branch of computer science that dealswith writing computer programs that cansolve problems creatively

I.e. imitation or duplication of intelligencein computers and robots

the science and engineering of makingintelligent machines.
