https://mathematica.stackexchange.com/landing/r/digest?cta=question&id=226316

Without any obvious reason Mathematica started to emit a beep after each evaluation, even when it is error free. Why is that, and how can I turn it off? I tried restarting Mathematica to no avail, and  ...

6.15.1.7 Prony series with a large number of terms

https://mathematica.stackexchange.com/landing/r/digest?cta=question&id=226327

A Prony series is similar to a Fourier series but can have fewer terms. It takes the form 
$\sum_{i=1}^{M} A_i e^{\sigma _i t} \cos \left(\omega _i t+\phi _i\right)$ 
Note that unlike Fourier series  ...
