@danadam We are talking about one. :relaxed: There is no argument between us. I just illustrated that the result is a sine wave. @71 dB We who agree with each other, why do we argue? I took the pictures for @sunjam. He tends to go in the wrong direction... :relaxed:

You misunderstood what I wrote... I have just demonstrated that quadrilateral signals are merely the sum of sinusoidal harmonics. There is no question of illegal signs. The first harmonic of 12 Khz is higher than the limit frequency.

In our area, they say it like this: He drinks wine and preaches water. :relaxed:

@sunjam This was the answer to your first post. I made it just for you...

When upsampling 44.1KHz, you will definitely use a 20 - 24KHz digital filter as a first step. After that it can be DSD or whatever...

If you can't lift 200kg, will you feel stronger if you can't lift 500kg? :relaxed:

You're getting really annoying! You're running in circles... Ignore is coming. :deadhorse:

Gregorio! I admire your patience! :relaxed:

DC initiates electrolysis in living tissues and blood (blood clot formation and blood blisters may form). The AC frequency disrupts the regulation of the heart's rhythm.

Yes. Any multimeter. Make sure that the maximum measurement frequency is 200-500 Hz. A higher frequency is not a problem, but the measurement accuracy decreases.

It's all bull... But what follows from this? How does this relate to sound? Do you want to create a cable miracle?

Yes, Yes... A real NOS DAC can only be multibit (R2R).
