I have doubts on Davids explanation too. Imagine a "perfect" ADC without DNL and noise and apply a linear voltage ramp to the input. Then the quanization noise should manifest with a...

In response to Achim; the ADC output is sampled-time, so all those harmonics alias back into the Nyquist zone in random places, unless the sawtooth and ADC sample frequencies are related. This makes...

View ArticleRe: Need 8 pole high pass filter with Butterworth response using SigmaDSP
As a footnote to this discussion, engineers do often design a multiple-pole filter by cascading filter blocks -- and yes, these sections are generally not identical. Given the desired overall...

With recent versions of SigmaStudio, the Stimulus/Probe response window works for all supported sample rates. Thus the workaround I described above is no longer necessary.
