| Mar 7, 2017 at 22:48 | comment | added | The Photon | Given you're sampling at 100 Hz and interested in signals below 5 Hz, I'd expect to get pretty good results by just interpolating in a value for the "bad" sample, based on the neighboring samples. | |
| Mar 7, 2017 at 22:39 | comment | added | jonk | There is a lot of literature on the missing value problem in FFT work. This is an area where I've spent some small time and there are a variety of tools you might apply, depending on what you know a-priori. Lagrange interpolation is one method. There are many others. NFFT is designed to handle non-equal spaced points, from the ground up, so you might examine it's methods, as well. Read its tutorial PDF. I would not recommend blindly setting missing values to anything. The surrounding data provides snapshots of reality that you should usually apply in some fashion. | |
