  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. Electronic media - Wikipedia

    en.wikipedia.org/wiki/Electronic_media

    The primary electronic media sources familiar to the general public are video recordings, audio recordings, multimedia presentations, slide presentations, CD-ROM and online content. Most new media are in the form of digital media. However, electronic media may be in either analogue electronics data or digital electronic data format.

  4. Analog observation - Wikipedia

    en.wikipedia.org/wiki/Analog_observation

    Analog observation is, in contrast to naturalistic observation, a research tool by which a subject is observed in an artificial setting. [1] Typically, types of settings in which analog observation is utilized include clinical offices or research laboratories, but, by definition, analog observations can be made in any artificial environment, even if the environment is one which the subject is ...

  5. Cyberpsychology - Wikipedia

    en.wikipedia.org/wiki/Cyberpsychology

    Cyberpsychology (also known as Internet psychology, web psychology, or digital psychology) is a scientific inter-disciplinary domain that focuses on the psychological phenomena which emerge as a result of the human interaction with digital technology, particularly the Internet.

  6. 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.

  7. Consumer electronics - Wikipedia

    en.wikipedia.org/wiki/Consumer_electronics

    Starting in the 1980s with the compact disc and the introduction of personal computers, and until the early 2000s, many consumer electronics devices such as televisions and stereo systems, were digitized: digital computer technology, and thus digital signals, were integrated into the operation of consumer electronics devices, drastically ...

  8. Audio signal processing - Wikipedia

    en.wikipedia.org/wiki/Audio_signal_processing

    An analog audio signal is a continuous signal represented by an electrical voltage or current that is analogous to the sound waves in the air. Analog signal processing then involves physically altering the continuous signal by changing the voltage or current or charge via electrical circuits.

  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.
