  2. Digital electronics - Wikipedia

    en.wikipedia.org/wiki/Digital_electronics

    Digital electronics is a field of electronics involving the study of digital signals and the engineering of devices that use or produce them. This is in contrast to analog electronics which work primarily with analog signals. Despite the name, digital electronics designs includes important analog design considerations.

  3. Digital signal conditioning - Wikipedia

    en.wikipedia.org/wiki/Digital_signal_conditioning

    Digital electronics is at the heart of computers, but there are many direct applications of digital electronics. All these digital electronics need data to be presented to them in a digital format (i.e. the data have to be digitally conditioned). This is called digital conditioning. Since computers are electronics devices, all the information ...

  4. Electronics - Wikipedia

    en.wikipedia.org/wiki/Electronics

    Modern surface-mount electronic components on a printed circuit board, with a large integrated circuit at the top. Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other electrically charged particles.

  5. Three-state logic - Wikipedia

    en.wikipedia.org/wiki/Three-state_logic

    In digital electronics, a tri-state or three-state buffer is a type of digital buffer that has three stable states: a high output state, a low output state, and a high-impedance state. In the high-impedance state, the output of the buffer is disconnected from the output bus, allowing other devices to drive the bus without interference from the ...

  6. Digital signal processing - Wikipedia

    en.wikipedia.org/wiki/Digital_signal_processing

    The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space, or frequency. In digital electronics, a digital signal is represented as a pulse train, [1] [2] which is typically generated by the switching of a transistor. [3]

  7. Signal integrity - Wikipedia

    en.wikipedia.org/wiki/Signal_integrity

    In digital electronics, a stream of binary values is represented by a voltage (or current) waveform. However, digital signals are fundamentally analog in nature, and all signals are subject to effects such as noise, distortion, and loss. Over short distances and at low bit rates, a simple conductor can transmit this with sufficient fidelity.

  8. Digital signal - Wikipedia

    en.wikipedia.org/wiki/Digital_signal

    A five level PAM digital signal. In digital electronics, a digital signal is a pulse amplitude modulated signal, i.e. a sequence of fixed-width electrical pulses or light pulses, each occupying one of a discrete number of levels of amplitude. [6] [7] A special case is a logic signal or a binary signal, which varies between a low and a high ...
