Ok, I have read the article and it doesn't make it much clearer for me. In fact, I want to know more!!!Exediron wrote:Here's a good article from RaceFans about the new sensor, which also explains in better detail what Ferrari may have been doing:
It sounds like Ferrari were using some sort of interference to fool with the sensor since they knew its precise measurement intervals."The new device incorporates anti-aliasing technology and full data encryption,” according to Sentronics. “The anti-aliasing technique randomises when the device makes its measurements, ultimately making it impossible to synchronise any ancillary parts to the measurement frequency. Full encryption ensures the authenticity of the data and privacy to the FIA."
The article does not say how they can make it work. The flow meter takes 2,200 measurements per second, so if I understand correctly, Ferrari somehow made the meter measure an "aliased" rate at all these 2,200 instances within a second. How would that be possible? (I am not an elec engineer, so any explanation would be appreciated!) They would need some kind of device to interfere with that signal, at these intervals and to create/show a lower value instead of the actual one? Aliasing is also easily avoided with Anti-Aliasing Filters from what I can gather, so if they had suspicions they could have added some sort of filters to cancel this interference fairly easily.
The article does not say how they did it, only that theoretically it would be possible. Much like saying it is possible in theory to make a flux capacitor, but can't actually make it to prove it.
Also statements like this one "One technician consulted by RaceFans estimated the potential power gained from aliasing could be as much as 50bhp" do not add much to be honest. A guy somewhere said something...
