A piece of measurement equipment which can visualize one or more signals simultaneously on a time scale.
The process of creating electronic products, including components and end-user devices.
A non-isolated DC-DC converter topology which outputs voltage less than or equal to the input voltage
Impedance defines the voltage/current characteristic of any dipole circuit.
Using other than a wired connection to transfer signals or power. Includes optical and (ultra)sound, but most often refers to RF (radio-frequent). Distances can be as low as centimeters (e.g. RFID), t…

Electrical device that converts direct current (DC) to alternating current (AC).
A digital signal that goes high and low at a specific frequency.
Circuit to generate a signal a specific time after a trigger event. The timing can be defined by an RC time constant, or by clock pulses from an oscillator.
the primary documentation about components, describing their functionality and electrical properties.
a low-cost PCB design software package.
Problems related to the connection of circuits to ground or earth references. Can affect safety, accuracy, reliability and interfacing.
Mains electricity, typically a higher voltage AC waveform used to deliver electrical power to households. In North America 120V, 60Hz, in most European countries 230V, 50Hz. What most people will pl…
A system that may be electronic circuits or even software that uses control theory (principally differential equations) to control an output by monitoring various aspects of the system under control a…
Questions related to the design of circuits that supply or use a high voltage. There are a few definitions but the IEC definition of a high-voltage supply system is above 1000 Vrms AC or 1500 V DC.
the assignment of numbers to objects or events. All measurements consist of three parts: magnitude, dimensions (units) and uncertainty.
An optoelectronic device which combines an optical transmitter and receiver in a single package; commonly used in galvanic-isolated control applications such as power supplies.
A non-isolated DC/DC converter topology.

a property of a substance related to the amount of heat energy it contains.
Questions about the electrical implementation of Ethernet; ask another Stack Exchange for software or protocol questions. Specify the speed as 10/100BASE-T is somewhat different from 1000BASE-T, apart…
a DC motor type that uses an electronic inverter/switching circuit to energize the motor coils in a sequence (based on the detected rotor position) in order to rotate…
a circuit that has two stable states and can be used to store state information.
How wires connect to terminals and to each other; coloring and organization schemes; appropriate wire selection and installation techniques
A kind of motor that moves in steps.
an integrated circuit (chip) used in a variety of timer, pulse generation and oscillator applications. The part is still in widespread use, thanks to its ease of use, low price and…
Surface-Mount Technology (SMT) refers to the way components are mounted on a PCB: SMDs (Surface-Mounted Devices) have pins or contacts which lay on top of the PCB's pads, without the need for holes in…
A chip or a circuit that sends a signal with more current or voltage, or over longer distances.
