Description
Experience Level: Intermediate
General information for the business: Preprocess dataset
Description of requirements/functionality: I’m going to process the data in non-overlapping windows. For example, if we have 5 seconds of motion sensor data and we divide it into windows lasting 0.25s each, we’ll have 20 windows, I’ve already created this window function.
next step (which I’d like someone to create a function to do this task), is to take one window at a time and pass them through a Fourier transform resulting in f frequency components, each with a magnitude and phase.
