  2. Comparison of analog and digital recording - Wikipedia

    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 ...

    Because of the relatively large size of the imaging area these media provide, they can record higher resolution images than most consumer digital cameras. Based upon the above pixel density, a medium-format film image can record an equivalent resolution of approximately 83 million pixels in the case of a 60 x 60 mm frame, to 125 million pixels ...

  5. Digital television transition in the United States - Wikipedia

    en.wikipedia.org/wiki/Digital_television...

    Digital TV encoding allows stations to offer higher definition video and better sound quality than analog, as well as allowing the option of programming multiple digital subchannels (multicasting). However, it provides these advantages at the cost of a severe limitation of broadcast range. [citation needed]

    This is because all analog receivers process analog signals faster than digital radios can process digital signals. The digital processing of analog signals in an HD Radio also delays them. The resulting unmistakable "reverb" or echo effect from playing digital and analog radios in the same room or house, tuned to the same station, can be annoying.

  7. Comparison of video codecs - Wikipedia

    Each compression specification defines various mechanisms by which raw video (in essence, a sequence of full-resolution uncompressed digital images) can be reduced in size, from simple bit compression (like Lempel-Ziv-Welch) to psycho-visual and motion summarization, and how the output is stored as a bit stream. So long as the encoder component ...

  8. Analog photography - Wikipedia

    en.wikipedia.org/wiki/Analog_photography

    Analog photography, also known as film photography, is a term usually applied to photography that uses chemical processes to capture an image, typically on paper, film or a hard plate. These processes were the only methods available to photographers for more than a century prior to the invention of digital photography , which uses electronic ...

  9. Digital photography - Wikipedia

    en.wikipedia.org/wiki/Digital_photography

    Digital photography uses cameras containing arrays of electronic photodetectors interfaced to an analog-to-digital converter (ADC) to produce images focused by a lens, as opposed to an exposure on photographic film. The digitized image is stored as a computer file ready for further digital processing, viewing, electronic publishing, or digital ...
