Analog transmission is not particularly efficient. When the signal-to-noise ratio of an analog signal deteriorates due to attenuation, amplifying the signal also amplifies noise. Digital signals are ...

Sigle signifiant Pulse Code Modulation. Système de codage numérique du son que l'on retrouve sur les CD en 16 bits et sur les DVD audio en 24 bits. La fréquence d'échantillonnage, exprimée en hertz, ...

L’Adaptive Differential Pulse Code Modulation (ADPCM) (en français, Modulation par impulsions et codage différentiel adaptatif (MICDA)) est un algorithme non ...

In MIPI Soundwire: Digital Audio Simplified, we mentioned that digital audio formats including Pulse Code Modulation (PCM) and Pulse Density Modulation (PDM) are target applications for MIPI Soundwire ...

L'ADPCM, ou Adaptive Differential Pulse Code Modulation, repose sur une technologie de compression audio conçue pour optimiser le rapport entre qualité sonore et espace de stockage. Contrairement au ...

La semaine dernière, nous avons publié deux articles détaillant les deux concepts les plus fondamentaux de la numérisation du son. Cette semaine, nous allons plonger encore un peu plus profond dans ce ...

Equipment is described which has been constructed for converting analogue television signals into 8-bit PCM signals and vice versa. The conversion rate used for video signals is approximately 13 ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

For technical and economic reasons, the present network of lines used for distributing sound signals to transmitters at audio frequencies will eventually have to be replaced by some telecommunication ...
