Fourier Transform in Qlik: Separating Signal from Noise


Good day, Data Explorers! In this video, we're exploring how to perform a Fourier Transform in Qlik. Whether you're experienced in data analysis or just starting, this video will guide you through uncovering periodic patterns in your time series data using Fourier Transforms.

We'll cover generating frequency indices, calculating the real and imaginary parts, and visualizing the magnitude of the frequency components in your Qlik app.
