A falling edge is the transition of a digital signal from a high voltage level (logic 1) to a low voltage level (logic 0). This downward transition oc...

A Field Effect Transistor (FET) is a semiconductor device that controls current flow between two terminals (source and drain) using an electric field ...

Filtering is the process of selectively allowing or blocking specific frequency components of an electrical signal while attenuating others. It is com...

Firmware is low-level software that is permanently stored in non-volatile memory (like flash memory or ROM) and provides the basic operational instruc...

Flash memory is a type of non-volatile electronic storage that retains data even when power is removed. It uses floating-gate transistors to store ele...

A flip-flop is a fundamental digital circuit that can store one bit of binary information (0 or 1) and maintain that state until deliberately changed ...

Flush cutters are specialized pliers designed to cut wires, component leads, and other materials as close to a surface as possible, leaving minimal pr...

Flux is a chemical cleaning agent used in soldering to remove oxidation and impurities from metal surfaces, ensuring proper solder joint formation. It...

A flyback diode is a protective diode connected in parallel with an inductive load (like a relay, motor, or solenoid) to suppress voltage spikes when ...

A footprint is the physical layout pattern that defines how an electronic component connects to a printed circuit board (PCB). It specifies the exact ...

A Force Sensitive Resistor (FSR) is a variable resistor that changes its resistance based on the amount of physical force or pressure applied to its s...

Frequency is the number of complete cycles or oscillations that occur in a periodic signal within a specific time period, typically measured in Hertz ...

A function generator is an electronic test instrument that produces various types of electrical waveforms over a wide range of frequencies. It can gen...

A fuse is a protective electrical component designed to interrupt current flow when it exceeds a predetermined safe level. It contains a thin metal wi...
