- hdgvhicv 4mo agoYes the high frequency noise. Depends on how good the hf filter is.
- chadgpt3 4mo agoWhy would you have one? Want the image to look blurrier on purpose? Color TVs have one to block the color dots.
- Majromax 4mo agoIf you're deliberately displaying the image in black and white, the colour pattern is interference that should be suppressed. However, this practice was not universal, and archivists have now recreated colour copies (https://en.wikipedia.org/wiki/Colour_recovery https://en.wikipedia.org/wiki/Colour_recovery) of some shows where only black and white recordings survived by reconstructing the colour from these interference signals.
- actionfromafar 4mo agoA very late in the signal chain color decoding. :-D
- ErroneousBosh 4mo agoThere's no real luminance content above about 5MHz, and TVs used to notch out the colour at 4.43MHz. As an aside, you can do all this digitally now with phenomenally sharp results.
