Composite 240p Performance

by Eli Krause

For composite decoding this set uses a Panasonic MN101E11GTD1, a 3-line digital comb filter/unified jungle chip. Depending on the console/revision, dot artifacting ranges from slight to severe, blending effects may be broken, and edge artifacts are slight to moderate. An example of the many dot artifacts are highlighted in the second picture below in red. Using an external notch filter to decode composite instead (such as is available in a RetroTink 2X, 5X, etc.) and sending that to the set's component input would blend all dithering patterns, reduce edge artifacts, and remove the dot artifacts.
