Printed circuit boardA printed circuit board (PCB), also known as a printed wiring board (PWB), is a laminated sandwich structure of conductive and insulating layers, each with a pattern of traces, planes and other features (similar to wires on a flat surface) etched from one or more sheet layers of copper laminated onto or between sheet layers of a non-conductive substrate. PCBs are used to connect or "wire" components to one another in an electronic circuit.
Monopole antennaClass of radio antennaA typical mast radiator monopole antenna of an AM radio station in Chapel Hill, North Carolina. The metal mast itself is connected to the transmitter and radiates the radio waves. It is mounted on a ceramic insulator to isolate it from the ground.
Antenna (radio)In radio-frequency engineering, an antenna (American English) or aerial (British English) is a structure used to convert alternating electric currents into radio waves for transmission, and to convert radio waves back into electric currents for reception. It is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver.
Whip antennaA whip antenna is an antenna consisting of a straight flexible wire or rod. The bottom end of the whip is connected to the radio receiver or transmitter. A whip antenna is a form of monopole antenna. The antenna is designed to be flexible so that it does not break easily. Whip antennas for portable radios are often made of a series of interlocking telescoping metal tubes, so they can be retracted when not in use.
Ground loop (electricity)In an electrical system, a ground loop or earth loop occurs when two points of a circuit are intended to have the same ground reference potential but instead have a different potential between them. This is typically caused when enough current is flowing in the connection between the two ground points to produce a voltage drop and cause the two points to be at different potentials. Current may be produced in a ground loop by electromagnetic induction.
Ground (electricity)In electrical engineering, ground or earth may refer to reference ground – a reference point in an electrical circuit from which voltages are measured, earth ground – an electrically neutral node that has a lot of available charges (e.g. the physical ground of Earth), or common ground – a common return path for electric current (also called neutral in electric power systems).
Power supplyA power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances that they power.
CrosstalkIn electronics, crosstalk (XT) is a phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel. Crosstalk is usually caused by undesired capacitive, inductive, or conductive coupling from one circuit or channel to another. Where the electric, magnetic, or traveling fields of two electric signals overlap, the electromagnetic interference created causes crosstalk.
TelecommunicationsTransmission of information electromagneticallyEarth station at the satellite communication facility Raisting Earth Station in Raisting, Weilheim-Schongau, Bavaria, GermanyTelecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electrical or electronic means, typically through cables, radio waves, or other communication technologies.
Electrical engineeringBranch of engineeringElectrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems that use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after the commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use.
EngineeringEngineering is the practice of systematically applying natural science and mathematics to design and improve systems, devices, or processes that solve problems under constraints. It is typically motivated by satisfying human needs, resulting in creations such as bridges, engines, smartphones, pacemakers, the internet, spacecraft, and washing machines.
Electrical conductorIn physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electric current) in one or more directions. Materials made of metal are common electrical conductors. The flow of negatively charged electrons generates electric current, positively charged holes, and positive or negative ions in some cases.*As an Amazon Associate I earn from qualifying purchases.
