— Relationships between spot size, pixel spacing, and shadow‐mask pitch are presented that ensure suppression of aliasing artifacts in digitally addressed CRTs. The suppression is effective not only at low spatial frequencies (moiré), but at all spatial frequencies up to the useful limit of the display (the Nyquist frequency).
