... with Macsyma & Mathematica around.However, if phase wasn't maintained the square wave would've never resolved. It would've oscillated instead because the HF correction waves would've been misaligned (out out phase with lower frequency base signal).
If however, your program is up & running, could you be so kind to run your program on a simple 44.1kHz sampling on a naturally damped 20Khz signal? I'd be very interested in how this is resolved.
BTW, if this is all done for oversampling, how does over sampling work so much better?
