I dropped a hint right there that the AC frequency is definitely not 60 Hz where I am.

- TylerE 7y agoActually you didn't. There were many countries that used PAL for TV broadcasts but have 60hz AC.
- aasasd 7y agoHmm, afaik the framerates were chosen to be equal to the AC freq so that there are no glitches in the image. Do those countries have converters or something in the TVs, or did they watch jumpy image?
- hunter2_ 7y agoThey didn't say PAL, they said "50 Hz TV." PAL and 50 Hz TV are not synonymous. Brazil has 60 Hz AC and uses PAL-M which is 60 Hz TV. AC=TV even in these odd cases. Old CRTs couldn't possibly clock their flyback to anything but mains.
