What's the FT of the input minus the output?
Posted by dave789 on March 13, 2012 at 06:26:21:
I see.
I am still curious what the Fourier transform (the theoretical FT)
of the difference,(
(the input, 1/44100 second length square pulse)
-
(the output of it by a typical DAC such as Benchmark DAC 1 in Fig. 1 in the Stereophile web page I linked before)
),
is.
How much content does the difference have below 20kHz?
