"WebMar 8, 2024 · 3. Unless your signal has zero mean, I would avoid zeroing the missing samples because that would introduce bias in the estimation of the mean, the power and the spectrum of the signal. Instead, the best estimation of the missing samples is the average value of your time series. However, using the mean isn't good either. " - Incomplete sampling
