Wide-area, digital transmission scheme used predominantly in Europe that carries data at a rate of 34.368Mbps. E3 lines can be leased for private use from common carriers.
Electro-Absorption Modulators: Chip-level modulation devices often integrated into hybrid transponder devices, alongside lasers.
Electrically controlled birefringence
Emitter-coupled logic
The simplest form of microprocessor supervisory circuit, it monitors the power supply for the microprocessor and provides only a power-on reset function.
Erbium-doped fiber-optical amplifier
Enhanced Data Rates for GSM Evolution: An enhanced modulation technique designed to increase network capacity and data rates in GSM networks. EDGE should provide data rates up to 384Kbps.
Electrically erasable programmable read-only memory
Electrical fast transient
Electronic Industries Alliance: Among other things, the EIA sponsors electrical and electronic standards.
Electronic Industries Association/Joint Electron Device Engineering Council
Materials studied and used mainly for their electrical properties. The electric response of materials largely stems from the dynamics of electrons, and their interplay with atoms and molecules.
A system in which the computer (generally a microcontroller or microprocessor) is included as an integral part of the system.
Electromagnetic Compatibility: The ability of electronic equipment to be a "good electromagnetic neighbor": It neither causes, nor is susceptible to, electromagnetic interference (within the limits of applicable standards).
Electromagnetic Interference: Unwanted noise from electromagnetic radiation.
An electrical enclosure is a cabinet for electrical or electronic equipment to mount switches, knobs and displays and to prevent electrical shock to equipment users and protect the contents from the environment.
Behavior of the device at the limit of temperature or voltage.
Encoder/Decoder
Energy harvesting (also known as power harvesting or energy scavenging) is the process in which energy is captured from a system's environment and converted into usable electric power. Energy harvesting allows electronics to operate where there's no conve
Electrical energy measurement basics.
Energy storage is the capture of energy produced at one time for use at a later time.
Effective Number of Bits: An indication of the quality of an analog-to-digital converter (ADC). The measurement is related to the test frequency and the signal-to-noise ratio.
Ethernet (-based) passive optical network
Erasable programmable read-only memory
Extinction ratio control
Electrostatic Discharge: Release of stored static electricity. Most commonly: The potentially damaging discharge of many thousands of volts that occurs when an electronic device is touched by a charged body.
Devices added to input and output pins on an IC to protect the internal circuitry from the damaging effect of electrostatic discharge.
Extended Superframe: A DS1 framing format in which 24 DS0 times lots, plus a coded framing bit are organized into a frame which is repeated 24 times to form a superframe.
Effective/Equivalent Series Inductance is the parasitic inductance in a capacitor or resistor.
Extended stack pointer
Effective Series Resistance (or Equivalent Series Resistance or ESR) is the resistive component of a capacitor's equivalent circuit.
A family of network protocols based on asynchronous frames. The Ethernet framing structure provides a flexible payload container with basic addressing and error detection mechanisms.
Electric Vehicle
Evaluation Kit (EV Kit, Development Kit): A printed circuit board with an integrated circuit and support components to produce a working circuit for evaluation and development. Most Evaluation Kits are fully assembled and tested.
Error Vector Magnitude: A measure of the difference between the (ideal) waveform and the measured waveform. The difference is called the error vector, usually referred to with regard to M-ary I/Q modulation schemes like QPSK, and shown on an I/Q "constell
EVSE is an abbreviation for Electric Vehicle Service Equipment, referring to a charging station.
Evaluation System: Evaluation kits that also include an interface board for connecting to a personal computer and Windows-based EVKit software.
Offered in some packages to improve thermal dissipation or lower the impedance of the ground connection. Normally not electrically isolated, it typically needs to be connected to a ground or power plane, depending on the device.
