### 03 - Cross Correlation
|
|
|
|
1. Simple Cross Correlation: Use the cross-correlation to detect and determine the time shift of two test events with one template event.
|
|
2. Enhanced Picker: This has been taken from the [ObsPy Tutorial](https://docs.obspy.org/master/tutorial/code_snippets/xcorr_pick_correction.html). ObsPy is licensed under the [LGPL v3.0](https://www.gnu.de/documents/lgpl-3.0.en.html)

### 04 - FFT, DFT and Applications
|
|
|
|
Interpolation and Deciamtion of Time Series using the DFT
|
|
|
|
### 05 - Spectrogram
|
|
|
|
1. Analysing dispersive signals. How to visualize changes in frequency content over time (moving window analysis, mutiple filter technique, instantaneous frequency, continuous wavelet transform, the uncertainty problem).
|
