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...
View ArticleRe: Need 8 pole high pass filter with Butterworth response using SigmaDSP
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.

Re: AD630 Unity gain error?
Harry Circuit is as below from AN-308. Supply voltage is +15/-15VDC. Signal input is on pins 16, 17; for test purposes I've connected a battery to the input. For comparator - Pin 10 is at GND and I...

I’ve checked on this and the abs max ratings on these datasheet are not “tested”. They come from the process parameters used for these parts. The 25degC test condition is not appropriate. The abs max...
View ArticleRe: ADAU1701 noisy sine waves
ADAU1701 full-scale output is 2.5Vpp, so 100mV is -29dBFS. With dynamic range of 104dB, that still leaves 75dB signal to noise, or 13 bit. Thus, quantization should not be the source of the noise...
