I agree 100 % UBER is preying on people that think they ' re making money or have figured out the game . All these you suck at ubering comments are laughable . Edit UBER is not a religious organization lolz <| sep |> If you ' re equating this with a presidency , I don ' t know what to say . This has no appreciable consequences in real life . <| sep |> Tell you what ? <| sep |> Perfect reconstruction does not require a signal to be periodic . Think about it in the frequency domain , a sampled signal simply creates replicas of itself at multiples of the sampling frequency . Hence a perfect low pass filter , can recover the original spectrum . The inverse is unique , as long as the frequency domain signal is L 1 integrable . Thus you can perfectly reconstruct the signal . With an infinite number of points . Still your point , that perfect reconstruction is not possible in practice , is a valid one . Also yes I should have said , if you restrict yourself to fixed time sampling , you must sample at strictly greater than twice the highest sampling frequency .
