Bandwidth


The RLC circuit may be used as a bandpass or band-stop filter by replacing R with a receiving device with the same input resistance. In the Series case the bandwidth (in radians per second) is



Alternatively, the bandwidth in hertz is



The bandwidth is a measure of the width of the frequency response at the two half-power frequencies. As a result, this measure of bandwidth is sometimes called the full-width at half-power. Since electrical power is proportional to the square of the circuit voltage (or current), the frequency response will drop to at the half-power frequencies.

[edit] Q factor

The Q factor can be expressed in terms of the three devices in the circuit, from the basis of the definition:

... and electronic circuits.

Electrical engineering, often referred to as the electrical and electronic engineering (EEE), is a field of engineering that generally deals with the study and application of electricity, electronics and electromagnetism. It is a very broad area that encompasses the design and study of various electrical & electronic systems, such as electrical circuits, generators, motors, transformers, magnetic devices & materials, other electromagnetic/electromechanical devices, electronic devices, electronic circuits, electronic materials, optical fibers, optoelectronic devices, computer systems, radio, television, telephony, telecommunications, wireless, microwave systems, mobile telephony, radar, data communication, computer networking, nanotechnology, photonics, etc.

Electrical engineering may or may not include electronic engineering. Where a distinction is made, usually outside of the United States, electrical engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control, whereas electronic engineering deals with the study of small-scale electronic systems including computers and integrated circuits.[1] Alternatively, electrical engineers are usually concerned with using electricity to transmit energy, while electronic engineers are concerned with using electricity to transmit information.

The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical power supply. The modern Electrical Engineering subject may cover a range of subtopics including power, microelectronics, VLSI, nanotechnology, control systems, mechatronics, robotics, nonlinear systems, computer engineering, systems analysis, signal processing, telecommunications, data communications, communication systems, information theory

telecomunication

Telecommunications has become one of the most important infrastructures that are very essential to the socio-economic well-being of any nation. The globalization of world economy has further amplified the importance of telecommunications to the economy. The telecommunication sector is one of the fastest-growing. Telecommunications is at a crossroads, local telephone companies threatened by wireless communication. Voice over IP challenges established structures of pricing and taxation
