What is the minimum frequency an FM carrier signal must be in order to
transmit uncompressed luminance [Y] video signals with the least
degradation in video quality?
If you mean devoid of interference, it would depend where you live and over
what range.
Isn't FM immune to interference? It's AM that is full of magnetic
disruptions.
No form of radio transmission or modulation is immune to interference. A well
designed FM detector will have good rejection of amplitude variations, but
there's no such thing as a perfect detector, and sufficiently strong amplitude
interference will contain some variable frequency components anyway.
