Sweet video Chris!! 9:40 - one minor thing: -3db is 71% of the signal amplitude gets through. It is 50% of the signal power, but we are not interested in power. Power doesn't mean anything in this application. That was a common confusion even with some lead devs till about 3-yrs ago.

@@PIDtoolbox Should be fine because you are looking at the power spectrum, not amplitude spectrum. Problems only arise when comparing power to amplitude. You'd need to compensate for the square root (or the squaring, looking from the other way), so you'd need to multiply by 2, like UAV Tech pointed out. Power ~ Intensity^2

Gotcha, thx guys. Yes, there’s a amp^2 and multiply by 2 in there in a previous step so that’s good. I’ve compared it directly to various other Matlab build in functions and it gives the same result.

Using the waterfall prooved super essential to find my right filters. Thanks for explaining even a bit more on how these betaflight filters actually work. What I would find good: Could you show how it looks when your filters work properly? Like showing before-after waterfall graphs and also some gyro+pid graphs? I got the noise of my quad down significantly, but still have the feeling that the signal to the motors is kinda noisy and thus wasting a ton of energy. But a bit of noise in that motor-signal seems ok if I look at UAV tech logs? Hard to judge!

Man you are an excellent teacher... I watched your video carefully and I finally understood how filters work and their applications, definitely. Thank you very much!!!

@@ChrisRosser no it does not. Help me understand what filtering does please. It filters out vibrations from the motors,frame and props so the gyro on the flight controller still feels them but compensates for the vibrations when you fly so your whole flight experience is smoother. Is that the goal? To not have prop wash and whatnot?

Hi Chris, I did this with my catalyst machineworks shocker tank, I did to mine, that which I asked about yours below, ie tightening up the min and max for dynamic notch and D-term, leaving a 25hz margin either side. I also noticed that my motor noise only showed 2 harmonics within the band range on explorer so dropped to 2 accordingly. Also no gyro filters as gyro debugging showed nothing. I have to say, even with deliberately abused props with extra notches (small) & some tips cut off, it still flew fine, not even warm motors and totally clean charts for gyros. FANTASTIC m8, thank you so much. Cant wait for pid tuning, coming soon. Best wishes to you

Fantastic work. I 100% agree with this logical approach and strategy. D term is the limiting factor and just randomly cranking it up to cope with frame resonances and motor noise just leads too disaster. Only really experienced pilots can get anywhere near a great tune by feel - I'm not one of them. A quantitative approach is the best way. Watching you and UAV Tech over the past few months has totally consolidated my existing knowledge and I can now fine tune with 100% success. One thing I'd add, just flying on default BF filter and pid settings and then analysing the data is perfect for 5 inch. But something , say with ducts and a poor frame build can fry motors extremely quickly. I always do a quick LOS shakedown flight in the garden for a minute and check temps for before heading out for the first proper tuning flight. If they're not stone cold something needs looking at.

Thanks Chris, this is awesome. Finally after over a year in this hobbie, someone has explained filters to me in a way that i can understand and that makes sense. Now, hopefully, i can tune my filters and pids and get a good flying quad without smoking any more motors, or at least not as often. Thanks for coming aboard and helping us all out with your vast knowledge. Thanks so much.
