FFT on a signal with a length that is not a multiple of the period of its harmonics
I was very surprised to find an apparent limitation to a FFT on a simple signal.
Let's consider a timeseries made of L=100 points, and simply composed of the sum of two sinus waves: one with a ...

Determine Sample Size for Sensor Data
I'm trying to determine the bias on a gyro that is under constant motion. The way I've been doing this is sampling it over a long period (~1 minute at 100Hz) and taking the average. However, if there ...

Why can't we use the Neyman-Pearson likelihood ratio directly?
If you have a bunch of events and would like to choose a cut to distinguish background and signal, you can take the likelihood ratio
$$
\lambda(\vec x) = \frac{f(\vec x| s)}{f(\vec x| b)}
$$
and the ...
