Hva er forskjellen på upsampling og oversampling?

Den sinc-formelen gir en frekvensrespons som ser slik ut:Regarding NOS: such converters have a frequency response of sin(pi*f/fs)/(pi*f/fs). This causes its characteristic sound. A friend of mine who is a mastering engineer once came raving about some box by Altmann. So I told him to upsample his audio 2x, then mix it with itself shifted 1 sample, take it back down 2x and listen what it does on a real DAC. The result was as predicted. This signal through his normal DAC sounded exactly like the original signal through the Altmann. Theory wins, again.
