Difference Between Electrical Engineering And Computer Science – Electronics is a subfield of electrical engineering that emerged in the early 20th century and is characterized by the use of additional active components, such as semiconductor devices, to amplify and control the flow of electrical current. Previously, electrical engineering used only passive devices such as mechanical switches, resistors, inductors, and capacitors.

Covering areas such as analog electronics, digital electronics, consumer electronics, embedded systems, and power electronics. He is also involved in many related fields, including solid state physics, radio engineering, telecommunications, control systems, signal processing, systems engineering, computer engineering, instrumentation engineering, power control, photonics, and robotics.

Difference Between Electrical Engineering And Computer Science

The Institute of Electrical and Electronics Engineers (IEEE) is one of the most important professional societies for electronics engineers in the United States. The equivalent body in the UK is the Institute of Engineering and Technology (IET). The International Electrotechnical Commission (IEC) publishes electrical standards, including standards for electronics engineering.

Electronics engineering as a profession emerged following the identification of the electron in 1897 and the subsequent invention of the vacuum tube, which could amplify and rectify small electrical signals, marking the beginning of the field of electronics.

Practical use began in the early 1900s with the invention of the diode by Ambrose and Fleming and the triode by Riede and Forrest, allowing non-mechanical devices to detect small voltages such as radio signals from radio antennas. Did. The development of electronics was rapid. By the early 1920s, commercial radio broadcasting and communications had become widespread, and electronic amplifiers were being used for a variety of applications, including long-distance telephone calls and the music recording industry.

This discipline was further strengthened by the massive development of electronic systems such as radar and sonar during World War II and the peacetime consumer revolution that followed.

Electronic signal processing deals with the analysis and manipulation of signals. A signal can be either analog, where the signal changes continuously in response to information, or digital, where the signal changes in response to a series of discrete values ​​representing the information.

Things You Never Knew About Electrical Engineering

For analog signals, signal processing may include amplification and filtering of audio signals in the case of audio equipment, and modulation and demodulation of radio frequency signals in the case of telecommunications. For digital signals, signal processing may include compression, error checking and detection, and correction.

Telecommunications engineering deals with the transmission of information through media such as coaxial cables, optical fibers, and free space. Transmission through free space requires information to be encoded onto a carrier wave and transmitted. This is known as modulation. Common analog modulation techniques include amplitude modulation and frequency modulation.

Once the transmission characteristics of a system are determined, telecommunications engineers design the transmitters and receivers needed for such a system. These two may be combined to form a two-way communication device known as a transceiver. An important consideration in transmitter design is power consumption, which is closely related to signal strength. If the signal strength of the transmitter is insufficient, the information in the signal will be destroyed by noise.

Avionics and aviation telecommunications engineering are concerned with aerospace applications. Aviation communications engineers include professionals who work on avionics for aircraft or ground equipment. Professionals in this field primarily require knowledge of computers, networks, IT, and servers. These courses are offered at aviation technical schools and other institutions.

Computer Engineering Vs. Electronics Engineering

Control gearing has a wide range of electronic applications, from the flight and propulsion systems of commercial aircraft to the cruise controls of many modern automobiles. It also plays an important role in industrial automation. Control engineers often use feedback when designing control systems.

Equipment operations deals with the design of devices that measure physical quantities such as pressure, flow, and temperature. Designing such equipment requires a thorough understanding of electronics operations and physics. For example, radar guns use the Doppler effect to measure the speed of oncoming vehicles. Similarly, a thermocouple uses Peltier’s Seebeck effect to measure the temperature difference between two points.

Instruments are often not used on their own, but as sensors in larger electrical systems. For example, you can use a thermocouple to maintain a constant temperature in your furnace. For this reason, instrumentation engineering is often considered the equivalent of control engineering.

Computer engineering deals with the design of computers and computer systems. This may include designing new computer hardware, designing a PDA, or using a computer to control an industrial plant. This area also includes the development of embedded systems (systems created for specific tasks, such as mobile phones). This field includes microcontrollers and their applications. Computer technicians may also work on the software of systems. However, the design of complex software systems often falls under the domain of software engineering, which falls under computer science and is usually considered a separate field.

VLSI Design Process VLSI means very large scale integration. We manufacture ICs and various electronic components. When designing an integrated circuit, electronics engineers first create a schematic that specifies the electrical components and describes the interconnections between them. Once complete, VLSI engineers convert the schematic into a working layout, mapping out the various conductor and semiconductor material layers needed to build the circuit.

Electronics is a subfield within the broader discipline of electrical engineering. Electronics engineers typically have a degree with a major in electronics technology. The study period for such degrees is typically three or four years, and depending on the university, the completed degree may be designated as a Bachelor of Engineering, Bachelor of Science, Bachelor of Applied Science, or Bachelor of Technology. Many universities in the UK also offer a Master of Engineering (Mg) degree at postgraduate level.

Some electronics engineers choose to earn a graduate degree such as a Master of Science, a Doctorate of Engineering Philosophy, or a Doctorate of Engineering. Some European and American universities have introduced the master’s degree as a first degree, and it is often difficult to distinguish between engineering and graduate and postgraduate study. Experience is considered in these cases. A master’s degree consists of research, coursework, or a mixture of the two. The Doctor of Philosophy consists of a significant research component and is often considered a touchstone into academia.

In most countries, a bachelor’s degree in engineering is the first step toward certification, and the degree program itself is accredited by a professional organization. Certification allows engineers to legally sign off on plans for projects that impact public safety.

Electrical Engineering Degree (bs)

After completing an accredited degree program, technicians must meet various requirements, including work experience requirements, before becoming certified. Qualified engineers are given the titles of Professional Engineer (USA, Canada, South Africa), Chartered Engineer or Corporate Engineer (UK, Ireland, India, Zimbabwe), and Chartered Professional Engineer (Australia and Zimbabwe). New Zealand) or European Engineers (most of the European Union).

Electronics degrees typically include units that cover specific topics in physics, chemistry, mathematics, project management, and electrical engineering. Initially, such topics will cover most, if not all, of the subfields of electronics engineering. A researcher chooses to specialize in one or more of her subfields towards a degree.

The basis of this field is physics and mathematics, which help explain qualitatively and quantitatively how such systems work. Today, most engineering work involves the use of computers, and it is common to use computer-aided design and simulation software programs when designing electronic systems. Most electronic engineers understand basic circuit theory, but the theory that engineers use generally depends on the work they do. For example, quantum mechanics and solid state physics may be relevant to engineers working on VLSI, but are largely irrelevant to engineers working on embedded systems.

Apart from electromagnetism and network theory, other items in the syllabus are specific to electronics engineering courses. Electrical engineering courses also include other specializations such as mechanical, power generation, and power distribution. This list does not include advanced engineering mathematics curriculum, which is a prerequisite for the degree.
