Hi,
Until yesterday I would have bet everything that a passive mixer, driven by 25% duty cycle gets rid of the 3rd, 7th, 9th etc harmonic; while the 50% version has all odd-order harmonics. I swear I have read this in about every single paper in that area so that I started assuming it "granted common knowledge" without ever actually verifying it.
Now in my simulations this is not the case and indeed, verifying a sinusoid wave, sampled 4x per period with zero-order hold all all odd order harmonics, same as the 50% version ("rectangular wave").
I am also desperately trying to find sources for that but I fail. The closest to that is https://icd.ewi.utwente.nl/temp_files/c2ee0ea0185d31e7ef31b0f6b7aaf6c0.pdf, slide 10.
Can anyone help to find out what could I mixing up here?
Thanks!
PS: In case my question is unclear or it is not entirely clear what I mean I am happy to provide simple MATLAB scripts comparing the spectra between 50% and 25% mixer
