Sounds right. In my case I was interpolating if f domain though. I expected to get zero padding in time.Unfortunately my figures that i inserted in one of my...

Can you explain what you mean? If you are interpolating complex numbers in f domain, you can do linear (default in Matlab) or nearest neighbor or other like spline...

Yes, but only if your freq bin size didn't change. I made some plots in Matlab. Starting with a short section of sine wave:Zero padding in f domain gives the expected...

Got it, thanks. Interpolating in one domain is zero padding in the other. I haven't thought about this stuff for a ling time!

OK, so if you zero pad, then Fs is increased proportionately, and, yes your IR has more points, but higher Fs = same length. But, if you add more points in the...

I was maybe being a little loose with terms. I really mean a DFT, Im just used to calling it FFT. You could calculate it in several different ways, FFT being...

Yes, I ws trying to figure out how to do it without needing to decimate, but in the end it is simpler to just do it that way!

I may not have been clear as to when I was talking about frequency values or indices. In my zero padded version (yes, not required except I wanted to get more...

I've done this a few times over the years (I used to do it more often), and it always seems like there ONE bin off somewhere that screws it up. For years, I just...
