  2. Comparison of analog and digital recording - Wikipedia

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

    The dynamic range of an audio system is a measure of the difference between the smallest and largest amplitude values that can be represented in a medium. Digital and analog differ in both the methods of transfer and storage, as well as the behavior exhibited by the systems due to these methods.

    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.

  5. Digital data - Wikipedia

    en.wikipedia.org/wiki/Digital_data

    Digital clock.The time shown by the digits on the face at any instant is digital data. The actual precise time is analog data. Digital data, in information theory and information systems, is information represented as a string of discrete symbols, each of which can take on one of only a finite number of values from some alphabet, such as letters or digits.

  6. Digital recording - Wikipedia

    en.wikipedia.org/wiki/Digital_recording

    Recording. The analog signal is transmitted from the input device to an analog-to-digital converter (ADC).; The ADC converts this signal by repeatedly measuring the momentary level of the analog (audio) wave and then assigning a binary number with a given quantity of bits (word length) to each measurement point.

  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 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.

  9. Analogue electronics - Wikipedia

    en.wikipedia.org/wiki/Analogue_electronics

    Analogue electronics (American English: analog electronics) are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two levels. The term analogue describes the proportional relationship between a signal and a voltage or current that represents the signal.
