Digital electronics

In digital logic and computing, a counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock signal.

In electronics, a Schmitt trigger is a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier.

In computer architecture, a bus (a contraction of the Latin omnibus) is a communication system that transfers data between components inside a computer, or between computers.

In digital circuit theory, combinational logic (sometimes also referred to as time-independent logic) is a type of digital logic which is implemented by Boolean circuits, where the output is a pure function of the present input only.

In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information.

In electronics, logic synthesis is a process by which an abstract form of desired circuit behavior, typically at register transfer level (RTL), is turned into a design implementation in terms of logic gates, typically by a computer program called a synthesis tool.

A microcontroller (or MCU, short for microcontroller unit) is a small computer (SoC) on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals.

A microprocessor is a computer processor which incorporates the functions of a computer's central processing unit (CPU) on a single integrated circuit (IC), or at most a few integrated circuits.

Transistor–transistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJTs) and resistors.

Hybrid computers are computers that exhibit features of analog computers and digital computers.

In computing, a programmable interrupt controller (PIC) is a device that is used to combine several sources of interrupt onto one or more CPU lines, while allowing priority levels to be assigned to its interrupt outputs.

Message Signaled Interrupts (MSI) are an alternative in-band method of signaling an interrupt, using special in-band messages to replace traditional out-of-band assertion of dedicated interrupt lines.

A leading zero is any 0 digit that comes before the first nonzero digit in a number string in positional notation.

In electronics, crosstalk is any phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel.

In digital circuit design, register-transfer level (RTL) is a design abstraction which models a synchronous digital circuit in terms of the flow of digital signals (data) between hardware registers, and the logical operations performed on those signals.

Bit slicing is a technique for constructing a processor from modules of smaller bit width.

Parametron is a logic circuit element invented by Eiichi Goto in 1954.

In digital circuits, a logic level is one of a finite number of states that a digital signal can have.

In electronics and computing, a soft error is a type of error where a signal or datum is wrong.

A glitch is a short-lived fault in a system.

Semiconductor memory is an electronic data storage device, often used as computer memory, implemented on a semiconductor-based integrated circuit.
