Check right below for a dogmatic assertion that the "sinc function is only in the time domain" or something to that effect.He is completely unable to see that the frequency dual shows precisely that you can get an aperiodic anything by simply setting the period to infinity.
He denies that one can apply a sinc in frequency, and insists in audio that sincs are only used in the time domain, and then only as part of a filter design method.
I appreciate your help, but he's not listening. Rather than listen, absorb, and learn, he aggressively spews the same mistakes he's been spewing roughly forever.
