Calculate FFT and Frequency Domain

  • Share this:

Code introduction


This function calculates the Fast Fourier Transform (FFT) of the input signal and returns the transform results along with the corresponding frequency domain.


Technology Stack : SciPy library's numpy and signal modules

Code Type : Mathematical calculation

Code Difficulty : Intermediate


                
                    
def calculate_fft(input_signal, sampling_rate):
    import numpy as np
    from scipy.signal import fft

    # Calculate the Fast Fourier Transform (FFT) of the input signal
    fft_result = fft(input_signal)
    frequency_domain = np.fft.fftfreq(len(input_signal), d=1/sampling_rate)

    return fft_result, frequency_domain
