Occupied bandwidth

`bw = obw(x)`

`bw = obw(x,fs)`

`bw = obw(pxx,f)`

`bw = obw(sxx,f,rbw)`

`bw = obw(___,freqrange,p)`

```
[bw,flo,fhi,power]
= obw(___)
```

`obw(___)`

`obw(___)`

with no output arguments
plots the PSD or power spectrum in the current figure window and annotates
the bandwidth.

To determine the occupied bandwidth, `obw`

computes
a periodogram power spectral density estimate using a rectangular
window and integrates the estimate using the midpoint rule. The occupied
bandwidth is the difference in frequency between the points where
the integrated power crosses 0.5% and 99.5% of the total power in
the spectrum.
