Resample data in all traces of stream using Fourier method.
Parameters: |
|
---|
Note
This operation is performed in place on the actual data arrays. The raw data is not accessible anymore afterwards. To keep your original data, use copy() to create a copy of your stream object. This also makes an entry with information on the applied processing in stats.processing of every trace.
Uses scipy.signal.resample(). Because a Fourier method is used, the signal is assumed to be periodic.
Example
>>> st = read()
>>> print(st)
3 Trace(s) in Stream:

>>> st.resample(10.0)
>>> print(st)
