I don't understand it. What determines the carrier frequency of the computer? How does he change the amplitude of the signal?

- anfractuosity 9y agoThe signal appears on many different frequencies, so afaik they must be harmonics, I'm curious as to what is defining the base carrier frequency too as the code itself doesn't determine that really. Edit: I just saw lovelearning's explanation - https://news.ycombinator.com/item?id=16168969 https://news.ycombinator.com/item?id=16168969 "In this case, the copper traces connecting CPU to RAM on that particular computer are emitting EM radiation at a frequency of 1580 kHz." I think 1580kHz could just be one of the harmonics. I'm curious what defines the carrier, if it's a factor of the length of copper on the memory bus, clock frequencies etc?
