signal¶
Some general signal processing tools (FFT, correlation). Mostly textbook and reference implementations plus some utilities.
|
Build and apply a digital FIR filter (low-, high-, band-pass, band-stop). |
|
(Normalized) autocorrelation function (ACF) for 1d arrays. |
|
Lorentz window (same as Cauchy function). |
|
Simple straightforward complex DFT algo. |
|
Simple FFT function for interactive use. |
|
Like scipy.fft.pack.fft and numpy.fft.fft, perform fft along an axis. |
|
Convert size and resolution between frequency and time domain. |
|
Simple peak finding algorithm. |
|
Gaussian function. |
|
Lorentz window (same as Cauchy function). |
|
Mirror array arr at index 0 along axis. |
|
Return next odd integer to n. |
|
Pad an nd-array with zeros. |
|
Scale x to unity. |
|
Smooth N-dim data by convolution with a kernel kern. |
|
Welch window. |
