Matplot fft
WebThe Fourier transform is a powerful tool for analyzing signals and is used in everything … WebExercise 1(b): Write a function to use a FFT to apply a low-pass filter to the data. You filter should have a time constant $\tau = 5$ seconds. Make a plot of the original data along with the filtered data. Note: When using np.fft.ifft(), it will return a complex-valued array even if the data has no imaginary component (as it should if you have done your filtering correctly).
