RE: Window overlap in Welch periodogram [ reply ]

Dear Bruno,

The shift parameter specify how many seconds the window is shifted for each spectrum calculation, this is not a %.

For instance, size=120, shift=30 corresponds to windows of 2 minutes (120 seconds) shifted 30 seconds in each iteration. This corresponds to a 75% of overlap because each windows overlap 90 seconds.



Window overlap in Welch periodogram [ reply ]

When performing a frequency analysis with "CalculatePowerBand" what is the % of overlap of moving windows (these with width specified by "shift" )?
Can we change this parameter ?
