Filters for Signal1D

These examples use Signal1D objects. Such signal can be used for a lot of applications where time is recorded on a single sensor (e.g. EEG, MEG). They can also represent these data in the frequency domain.

• Compute the 1D Fourier transform and inverse transform on a signal | source

The two following are doing basically the same but the first using two filters (one for lo, one for hi), while the second uses a single filters that takes two cutoff frequencies:

• Performing a high-pass and/or low-pass filter in Fourier domain (EEG) | source
• Performing a band pass filter in Fourier domain (EEG) | source

• Performing a high-pass and/or low-pass filter using difference equation and convolution (EEG) | source
