Reproduction of Low-Frequency Square Waves by Audio Amplifiers (and DAC)

[nagster]

Well hes mostly right. He was wrong about the tilt, its from the 10hz hipass filter he has on, not the lopass, so yes like a coupling cap. He also said a perfect square wave has infinite power, which is also wrong. Its power is the same as a DC voltage with the same level. I agree mostly with what he says but I still like to see it.

I am not good at English so this was very helpful. Thank you.
