WebThe Details¶. There are several functions in the numpy and scipy libraries that can be used to apply a FIR filter to a signal. From scipy.signal, lfilter() is designed to apply a discrete IIR filter to a signal, so by simply setting the array of denominator coefficients to [1.0], it can be used to apply a FIR filter. Applying a FIR filter is equivalent to a discrete convolution, so … Web1.10.1 GitHub; Twitters; Clustering package ( scipy.cluster ) K-means clustering and vector-based quantization ( scipy.cluster.vq ) Hierarchical clustering ( scipy.cluster.hierarchy ) Constants ( scipy.constants ) Datasets ( scipy.datasets ) Discrete Etc transforms ( scipy.fft ) Legacy discret Fourier transforms ( scipy.fftpack )
