The Pope is ALWAYS old: Nyquist Sampling Theorem

The Nyquist sampling theorem states that, to accurately re-construct a band-limited signal, one must sample at twice the highest frequency that's present in the signal. This way you capture accurately the highest frequency with good fidelity. But what is not often taught about digital sampling is that you must also SAMPLE LONG ENOUGH to capture the LOWEST frequency! If you were born after 1980, it would appear as a fact to you that the Pope has always been old. You sampled fast enough to catch the high frequency of a changing Pope, but you didn't get the low frequency of the Pope once being young. Since the period of the Pope being young is greater than 25 years or so, it didn't get captured because you didn't sample for 25 years.

Why do we sing Take Me Out To The Ball Game when we are already there? Actually there were verses to that song and nowadays we just sing the chorus. Again, we didn't sample long enough.

All the negative comments prove that you did a good job Amishman35 xD

[ofembe]

You didn't explain why.It should be because of aliases.Ugh

[TheMrChugger]

Yes, but that doesn't explain why we'd have to sample double what we can hear?!

[Lepiratepoulpe]

also...could we tweek our brain to catch frequencies we sould not? This theory is a pandora box for metaphisical, paranormal and spiritual understanding....Have i smoked too much weed ? Now you tell me. =)

[Lepiratepoulpe]

if i get it right ...i could use this to create an hologram of some sort to cover my real identity. If the frequency is not stable enough due to magnetic or supra phisical phenomenas...could i shiftshape ? Very interesting !

[kurisux]

This is actually really good, in a backwards sort of way.

Very good point: we may miss subtle ultra subsonic frequencies, which would help to fill music. Hmn....

[hypnotekk]

shame your genius in Avionics doesn't extend into grammar.

[Avionicgenius]

I was talking about two people...

No need for you slander thank you

[hypnotekk]

that's "Claude Shannon", dumbass.

[Xiyad]

The sampling frequency should be greater than twice the bandwidth of the input signal in order to reconstruct the orignal signal as an output signal from the sampled version.

That is alllllllllllllllllllllll i know,
