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 ...
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 ...
Digitizing, or converting analog signals into digital form, was first developed in 1903 with the invention of pulse-code modulation (PCM) for telephone communications. [13] Electronic encryption, which allowed for the secure transmission of information over electronic channels, was developed between 1935 and 1945 and played a crucial role in ...
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.
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.
It could be the transfer of an analog signal, using an analog modulation method such as frequency modulation (FM) or amplitude modulation (AM), or no modulation at all. Some textbooks also consider passband data transmission using a digital modulation method such as ASK, PSK and QAM, i.e. a sinewave modulated by a digital bit-stream, as analog ...
This continuous (or "analogue") aspect of the scale differentiates it from discrete scales such as the Likert scale.There is evidence showing that visual analogue scales have superior metrical characteristics than discrete scales, thus a wider range of statistical methods can be applied to the measurements.
Digital phenotyping is a multidisciplinary field of science, [1] [2] [3] first defined in a May 2016 paper in JMIR Mental Health authored by John Torous, Mathew V Kiang, Jeanette Lorme, and Jukka-Pekka Onnela as the "moment-by-moment quantification of the individual-level human phenotype in situ using data from personal digital devices."
