This function can generate a number of common 1D test signals used in papers by David Donoho and colleagues (e.g. [1]_) as well as the wavelet book by Stéphane Mallat [2]_. Parameters ---------- name : {'Blocks', 'Bumps', 'HeaviSine', 'Doppler', ...} The type of test signal to generate (`name` is case-insensitive). If `name` is set to `'list'`, a list of the available test functions is returned. n : int or None The length of the test signal. This should be provided for all test signals except `'Gabor'` and `'sineoneoverx'` which have a fixed length. Returns ------- f : np.ndarray Array of length ``n`` corresponding to the specified test signal type. References ---------- .. [1] D.L. Donoho and I.M. Johnstone. Ideal spatial adaptation by wavelet shrinkage. Biometrika, vol. 81, pp. 425–455, 1994. .. [2] S. Mallat. A Wavelet Tour of Signal Processing: The Sparse Way. Academic Press. 2009.
