    I'm looking for the explanation why non inverting low pass filter is not as good as the inverting low pass filter?
    Would you be kind make another video about it?

      Both are good, but the non-inverting filter has a minimum gain of 1 at all frequencies, while the gain of the inverting filter goes to 0 as f goes to infinity. That means that the inverting filter does a better job of rejecting high-frequency noise.
      I don't see the need for a video to provide a one-sentence explanation.

    The gain is -66 which you cannot convert to db. how do you get a positive db of 36.5

      For converting to dB, you take the *magnitude* of the gain and 20 log10(66) ≈ 36.5dB.
