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 … dishwasher brisbaneWebHere are the examples of the python api scipy.signal.firlstaken from open source projects.
