  1. Having much benefits using the AD2 during many years, I have now discovered that the power supply outputs having significant switching noise which depends on the output voltage and load at the power supplies! Unloaded it is wellknown that DC-DC power supplies can be pulse skipping and thereby cause low frequency switching noise. But even with reasonable loads the noisy behavior are still significant! Hereby a couple of measurements: Ch1: positive supply Ch2: negative supply Is it possible to reduce/remove this power supply noise? (Except of cause by heavy LP filtering).

  2. Hello everyone , Im a master student working on a school project , my task is to actually plot the noise spectral density of 2 signals using the program WAVEFORMS , and analyse their similarities using the mathematical methode : Cross spectral correlation . So if anyone has ideas how to implement this methode in waveforms through javascript . In matlab the function xcorr can do that , but im working with waveforms and the digilent discovery 2 so im not sure if i can import matlab files into that . I'll so much appreciate your help guys . Thank you !
