  • i like cheese!!!

  • you made a mistake in the very end from 3:00 to 3:21

    the wavelength should be marked, not the Hz because you explicitly said that a wavelength is defined as from one compression to an adjacent compression

  • GO SA

  • Good video - very clear. And amplitude represents the volume - right ?

  • 11;11

  • reminds me so much of my physics class damn awesome vid !

  • The DC offset can be regarded as a component added in the signal which has the frequency = 0.

    Although it's very common in electronics and signal processing, it can be found in real life if we go up the mountains and our eardrums are pushed a bit outwards by the air pressure difference, we say a negative DC offset was added. Even if we can't hear 0 Hz sounds, the elasticity and mobility (amplitude) of the eardrum will be reduced, thus the hearing drops. This until the pressure re-equalizes.

  • great vid

  • This is great.Thanks

  • great done
