# Data Denoising with Fast Fourier Filter¶

Non-Causal Step

This step applies the well-known Fast Fourier Transform algorithm to decompose a signal into its frequency components. The signal noise can be removed by suppressing the high frequency components.

Input Parameters

1. One-dimensional time series data
2. The cut-off frequency

Output Parameters

1. Denoised time series data
