I'd like to hear the full story of the decision to go with FM sound. The selection of FM meant that good audio could be received at signal levels way below what was needed for good video. AM sound would have resulted in sound and picture requiring about the same signal levels for acceptable performance. So, in a way, FM sound didn't really have any advantages over AM in television.
The reason wasn't intercarrier IF, since it didn't exist in 1941. And FM detectors were more complex than AM ones at the time.
Anyone know the full story why FM was chosen?
