OK ... Will read the whole article... ... In 16-bit, a -90dB sine wave will only have values of 0 (zero-crossing point) +full signal and -full signal. That's not a staircase, more a fact of life :-) essentially it's behaving more like a square wave... It's either full on or full off. No matter how hard we try, there's nothing to be done with such a simple representation of a waveform. The filter will still do what it always does which is to smear those voltage changes over time... The fact remains that what comes out of a DAC (assuming a more realistic number of bits!) is not a jagged staircase, but something that is largely indistinguishable from what went into the ADC in the first place. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
