The Television Scanning Process

G. J. Tonge

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.
