I was playing some emulator games, like sonic and super mario world, but even using filters and shaders, I felt that the experience was not complete. It was then that I remembered that ALL TVs I played with during my childhood had a typical noise, even with headphones on.
This noise was constant, but it changed according to what was displayed on the screen. The noise was typically a low frequency sine wave (it took about 15 or 20 seconds to complete the loop) but when the screen displayed white, the noise had a higher frequency, generating a "faster" sound. I distinctly remember this during the boot of my sega genesis, on the "licensed by sega" screen and then before showing the Konami logo.
To make it very clear, I'm not referring to the noise overdrive of the first models of the Sega Genesis, but the noise of the analog CRT TV (I don't remember if the digital CRT TVs also had it)
Note: With "Analog TVs" and "Digital TVs" I mean very old TVs that had 13 channels, and didn't have an OSD, and digital TVs like a little more modern TVs, that had OSD, channel+ and channel - buttons.
I know this noise must come from bad filtering, cheap design, or something. But I want to understand it, and try to recreate it in emulation
