TL;DR: Balayage considere comme un procede d'echantillonnage pour the conversion analogique numerique du signal de television en television numerique et techniques pour ameliorer la qualite d'image en augmentant le facteur de Kell.
Abstract: In the sampling of television signals for digital processing, a trade-off exists between maximum signal bandwidth and low aliasing distortion and filter ringing levels This is discussed in relation to television scanning, which in itself is a sampling procedure The Kell factor is reviewed, and techniques are outlined that will improve picture quality by increasing the Kell factor A compatible approach toward future improved television services is derived from these considerations
