A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.

A chip or a circuit that sends a signal with more current or voltage, or over longer distances.
the analysis, interpretation and manipulation of signals
Short for Liquid Crystal Display. LCDs consume little power, and exist in graphic LCDs, or segmented. The latter type is used for character and 7-segment digit display, and also in custom LCDs for con…
The ESP8266 is a low-cost Wi-Fi chip/module with UART connections and a built-in TCP/IP stack.
A multiplexer selects one of two (or more) inputs based on a control input. It then outputs the selected input.

Differential refers to any kind of signaling where the signal information is carried by two or more paths and both are required to properly reconstruct the signal. For example, USB D+ and D-
Low-power refers to electronics that are designed to use less power than their common counterparts. This is often a requirement because of limited available power, as in battery operated devices, or i…
Questions about the design of electronics for use in an automotive environment. (Questions about the installation and use of automotive electronics are unlikely to be appropriate for this site.)
Switching can be defined as the change in state whether it be an analog, digital, or mechanical device. For digital devices, switching can be defined as a transition from HIGH to LOW or vice versa. Fo…

These are part of AC to DC conversion. A half-wave rectifier keeps only the positive part of the signal. A full-wave rectifier also keeps the negative part, but flips it to make it positive too.
A multifunction measuring instrument used for measuring AC and DC voltage [V] and current [A] as well as resistance [Ω]. Many digital multimeters can also measure frequency [Hz], duty cycle [%], capac…
Electromagnetic compatibility (EMC) is a branch of electronics related to identifying and solving problems caused by electromagnetic interference (EMI) between devices. It encompasses both attempting …
More than one of a thing, performing the same task simultaneously
Ancillary circuitry added to a design that provides protection of the main circuitry to enable the main circuits continuing functioning. In some cases the protection circuitry is sacrificial, being d…

A generator is a device that generates electricity from mechanical energy via different energy sources such as heat or kinetic energy of water.
mechanically-adjustable special-type variable resistor with 3 legs and it is used as a potential-divider. (It is not a meter at-all, but got the name from its historical ancestor which was a meter.)

Zener is an effect in semiconductors, the name of a diode that uses that effect and more generally any diode that has similar characteristics to a Zener diode.
A type of bipolar transistor comprised of n-type semiconductor in contact with p-type semiconductor which in turn is in contact with a n-type semiconductor -> thus NPN. The transistor has three termi…
