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…
Questions about cable types, properties, ratings and construction.
Consider also the rf tag.
"Complementary Metal-Oxide Semiconductor" is a process which implements a combination of PMOS and NMOS transistors. Most current digital logic is implemented in CMOS. Its cost-effectiveness due to be…

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.
An electronic component that sources current - if it sinks current it is called a current sink but both devices (sinks and sources) can be called sources. An IDEAL current source will supply current …
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-
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.)
electromagnetic radiation with longer wavelengths than those of visible light at 0.74 micrometres (µm) to 300 µm, which is extends the nominal red edge of the visible spectrum.
a device that generates electricity from mechanical energy via different energy sources such as heat or kinetic energy of water.
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…
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…
Questions about programming parts (FPGAs, Flash, etc.) Many software programming questions should be asked instead on Stack Overflow.
Anything related to transfer functions, i.e. those complex-valued functions of a complex variable used to model mathematically the I/O relationship of linear time-invariant initially-at-rest system us…
A comparator compares two voltages or currents and switches an output to indicate which is larger.
Act of measuring voltage
the strength of an electric current in Amperes (Sometimes shortened to Amps).
an acronym for general purpose input/output. The term is typically applied to a pin on a microcontroller (or other device) that may be changed between an input and output under software contro…
