Composite 240p Performance
by Eli Krause
For composite decoding this set uses a Toshiba TC90A45FG, a dynamic 2-line digital comb filter introduced in 1997. Depending on the console/revision, dot artifacting ranges from moderate to severe, blending effects may be broken, and edge artifacts are mostly moderate to severe. An example of the many dot artifacts are highlighted in the second picture below in red. If the set has a higher bandwidth input such as component, then 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 would blend all dithering patterns, reduce edge artifacts, and remove nearly all dot artifacts.
