In telecommunications, the (digital) cliff effect or brick-wall effect is a sudden loss of digital signal reception. Unlike analog signals , which gradually fade when signal strength decreases or electromagnetic interference or multipath increases, a digital signal provides data which is either perfect or non-existent at the receiving end.
The simplest way to change the duration or pitch of an audio recording is to change the playback speed. For a digital audio recording, this can be accomplished through sample rate conversion. When using this method, the frequencies in the recording are always scaled at the same ratio as the speed, transposing its perceived pitch up or down in ...
For example, Compact Disc Digital Audio and Digital Audio Tape systems use different sampling rates, and American television, European television, and movies all use different frame rates. Sample-rate conversion prevents changes in speed and pitch that would otherwise occur when transferring recorded material between such systems.
A glitch (circled in red) occurring during circuit operation. Glitch removal is the elimination of glitches—unnecessary signal transitions without functionality—from electronic circuits.
Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.
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. The dynamic range capability of digital audio systems far exceeds that of analog audio systems. Consumer analog cassette tapes have a dynamic range of between 50 and 75 dB.
Dr. Rocco says that one change she wishes people 50 and older would make is getting adequate sleep and learning how to sleep better. “Valuing sleep and maintaining good sleep hygiene is essential.
Direct digital synthesis (DDS) is a method employed by frequency synthesizers used for creating arbitrary waveforms from a single, fixed-frequency reference clock. DDS is used in applications such as signal generation , local oscillators in communication systems, function generators , mixers, modulators , [ 1 ] sound synthesizers and as part of ...
