Default I want to see SHF FM video signals.

Hi:

Video signals for NTSC, PAL, and SECAM television are transmitted on
AM carriers.

My question is, let's say I have a television set that is capable of
receiving and demodulating FM video carrier waves. What would I see on
the TV? I am aware that no company uses FM video. Would I see sawtooth-
like patterns on the screen due to frequency-modulated electric fields
present in the environment?

No FM shf receiver is built for FM video, because there aren't any FM video
broadcast stations. If there was such a receiver and you tuned it to a
standard ntsc video carrier, you would probably see nothing (no sync, no
video), because the limiter stages would saturate and there would be no AM
output.


I'd really like buy a TV with a FM-video receiver; I want to find out
what FM-video disturbances in the SHF [Super High Frequency ]
frequency-range look like. I am sick n' tired of AM video.

AM should be used for analog audio. FM should be used for digital
video.

It's ok to have an opinion, but who do you suppose is won over by your
preferences?


Regards,

Radium
