Which itself is derived form the mains frequency of 50 or 60 Hz depending whether you're from the metric or the eagles/freedom land.
So the digital sample rate is related to how fast the power pant spins it's generator turbine.

- cesarb 3y ago> mains frequency of 50 or 60 Hz depending whether you're from the metric or eagles/freedom land. Sorry for nitpicking, but the huge country I live in uses metric but has 60 Hz for the mains frequency (and our analog TV standard is PAL-M).
- FirmwareBurner 3y agoCanada or Australia?
- foldor 3y agoPAL-M is Brazil as far as I know. Canada is still NTSC.
- rusk 3y agoVery interesting. From Wikipedia: https://en.m.wikipedia.org/wiki/PAL-M https://en.m.wikipedia.org/wiki/PAL-M > [PAL M] is unique among analogue TV systems in that it combines the 525-line 30 frames-per-second System M with the PAL colour encoding system (using very nearly the NTSC colour subcarrier frequency), unlike all other countries which pair PAL with 625-line systems and NTSC with 525-line systems. So presumably PAL M runs at 60 Hz just like NTSC, which again comes back to the domestic AC freq
