[chuck-users] analog to digital conversion simulation

[eduard aylon]

Hi kassen,

Thanks for the link. The sync filter is exactly what I am doing. I am  
applying a rectangular window in the frequency domain (so all bins=0  
above the specified freq), which in fact translates into a sync  
function in the time domain. This way is more efficient than  
convolving in the time domain with the sync function.
I'll have a look at your previous post, with more detail.

Yes, I also think so. I am hoping some experienced dsp guru in the  
list may have some tips.

thanks again,
