20kHz, 0db is indicated in diagram 12, and that of the comparing DAC in diagram 13. In diagram12, it seems like 22kHz square wave is under amplitude modulation at 4kHz, and no 20kHz can be seen. I am not sure if this is perceived as 20kHz when it is filtered through our auditory sense. I would like to hear opinions from psycho-acoustic professionals. Considering the limit of impairment perception of humans (around 200Hz), however, this amplitude modulation of 4kHz does not need to be worried about at all.
εχει δει κανεις αυτότο σημειο??? ή εγώ τα χω χάσει? (diag.12 nos, 13 os)
After examining the following two aspects, I came to a conclusion that 'it is quite difficult to carry out oversampling as theoretically under the current technology'.
ανευ σχολίου.
τελος το """κεφάλαιο""" digital filter problems που εχει μια "πολύ ωραία" ενστικτώδη ανάλυση ενός fir interpolation filter (μα ελεος.)
Βασικά.. ωραίο λογοτεχνικό άρθρο.. τεχνικό?

Βασικα η "αναλυση " του για τα φιλτρα πεπερασμενης αποκρισης ειναι το λιγοτερο ατυχης.:ernaehrung004:
Αλλα αυτο δεν αναιρει τα προβληματα που αυτα παρουσιαζουν
