For TV transimission in india we use AM for video and FM
for audio. why like this? can we use opposite way?

Answer Posted / durgak

AM can also be used for audio but since AM is more noisey
than FM, so FM is generaly used for audio.but in video
transmission, noise doesn't have much impact on video,also
cost implication is justified,since FM transmission is
costlier than AM transmission.
