  2. Comparison of analog and digital recording - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_analog_and...

    Early digital systems may have suffered from a number of signal degradations related to the use of analog anti-aliasing filters, e.g., time dispersion, nonlinear distortion, ripple, temperature dependence of filters etc. [20]: 8 Using an oversampling design and delta-sigma modulation, a less aggressive analog anti-aliasing filter can be ...

  3. Analog-to-digital converter - Wikipedia

    en.wikipedia.org/wiki/Analog-to-digital_converter

    ADCs are required in digital signal processing systems that process, store, or transport virtually any analog signal in digital form. TV tuner cards, for example, use fast video analog-to-digital converters. Slow on-chip 8-, 10-, 12-, or 16-bit analog-to-digital converters are common in microcontrollers.

  4. Integrated circuit design - Wikipedia

    en.wikipedia.org/wiki/Integrated_circuit_design

    Digital design focuses on logical correctness, maximizing circuit density, and placing circuits so that clock and timing signals are routed efficiently. Analog IC design also has specializations in power IC design and RF IC design. Analog IC design is used in the design of op-amps, linear regulators, phase locked loops, oscillators and active ...

  5. Digital control - Wikipedia

    en.wikipedia.org/wiki/Digital_control

    Digital control theory is the technique to design strategies in discrete time, (and/or) quantized amplitude (and/or) in (binary) coded form to be implemented in computer systems (microcontrollers, microprocessors) that will control the analog (continuous in time and amplitude) dynamics of analog systems.

  6. Digital video - Wikipedia

    en.wikipedia.org/wiki/Digital_video

    Sony digital video camera used for recording content. Digital video is an electronic representation of moving visual images in the form of encoded digital data.This is in contrast to analog video, which represents moving visual images in the form of analog signals.

  7. Data communication - Wikipedia

    en.wikipedia.org/wiki/Data_communication

    Data transmitted may be digital messages originating from a data source, for example a computer or a keyboard. It may also be an analog signal such as a phone call or a video signal, digitized into a bit-stream for example using pulse-code modulation (PCM) or more advanced source coding (analog-to-digital conversion and data compression) schemes.

  8. Digital signal - Wikipedia

    en.wikipedia.org/wiki/Digital_signal

    A digital signal is a signal that represents data as a sequence of discrete values; at any given time it can only take on, at most, one of a finite number of values. [1] [2] [3] This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.

  9. 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.
