When completed, VLSI engineers convert the schematics into actual layouts, which map the layers of various conductor and semiconductor materials needed to construct the circuit. The conversion from schematics to layouts can be done by software see electronic design automation but very often requires human fine-tuning to decrease space and power consumption.
Once the layout is complete, it can be sent to a fabrication plant for manufacturing. Integrated circuits , FPGAs and other electrical components can then be assembled on printed circuit boards to form more complicated circuits. Today, printed circuit boards are found in most electronic devices including televisions , computers and audio players.
February Electronic engineering has many subfields. This section describes some of the most popular subfields in electronic engineering; although there are engineers who focus exclusively on one subfield, there are also many who focus on a combination of subfields. Signal processing deals with the analysis and manipulation of signals. Signals can be either analog , in which case the signal varies continuously according to the information, or digital , in which case the signal varies according to a series of discrete values representing the information.
For analog signals, signal processing may involve the amplification and filtering of audio signals for audio equipment or the modulation and demodulation of signals for telecommunications. For digital signals, signal processing may involve the compression , error checking and error detection of digital signals.
Telecommunications engineering deals with the transmission of information across a channel such as a co-axial cable , optical fiber or free space. Transmissions across free space require information to be encoded in a carrier wave in order to shift the information to a carrier frequency suitable for transmission, this is known as modulation. Popular analog modulation techniques include amplitude modulation and frequency modulation. The choice of modulation affects the cost and performance of a system and these two factors must be balanced carefully by the engineer.
Once the transmission characteristics of a system are determined, telecommunication engineers design the transmitters and receivers needed for such systems. These two are sometimes combined to form a two-way communication device known as a transceiver. A key consideration in the design of transmitters is their power consumption as this is closely related to their signal strength.
If the signal strength of a transmitter is insufficient the signal's information will be corrupted by noise. Electromagnetics is an in-depth study about the signals that are transmitted in a channel Wired or Wireless. Its applications are seen widely in other sub-fields like Telecommunication, Control and Instrumentation Engineering.
Control engineering has a wide range of applications from the flight and propulsion systems of commercial airplanes to the cruise control present in many modern cars. It also plays an important role in industrial automation. Control engineers often utilize feedback when designing control systems. For example, in a car with cruise control , the vehicle's speed is continuously monitored and fed back to the system which adjusts the engine's power output accordingly. Where there is regular feedback, control theory can be used to determine how the system responds to such feedback.
Instrumentation engineering deals with the design of devices to measure physical quantities such as pressure , flow and temperature. These devices are known as instrumentation. The design of such instrumentation requires a good understanding of physics that often extends beyond electromagnetic theory.
For example, radar guns use the Doppler effect to measure the speed of oncoming vehicles. Similarly, thermocouples use the Peltier—Seebeck effect to measure the temperature difference between two points.
Often instrumentation is not used by itself, but instead as the sensors of larger electrical systems. For example, a thermocouple might be used to help ensure a furnace's temperature remains constant. For this reason, instrumentation engineering is often viewed as the counterpart of control engineering. Robert C. John J. Murray R. Luigi Bonaffini. Edward T. Alvin Halpern.
