# Fourier Transform

This is a demonstration of fourier transform and fourier inverse made in

python using the `scipy.fft` module (for educational purpose)

![Fourier transform demonstration](fft_demonstration.png "Fourier transform demonstration")

This demonstraion uses combination of 3 sine waves of frequency 2Hz, 4Hz and 8Hz.

You may play with the `driver.py` file to try this with other frequencies

```py

def f(x):

    x = 2*np.pi*x

    return (np.sin(2*x)+np.sin(4*x)+np.sin(8*x))

```

Just change the coefficient of x inside the sin functions to change the frequency.

You may also add more number of sin function by just adding more `np.sin` functions
