Folded spectrum method

The Folded Spectrum Method, often used in the analysis of astronomical data, particularly in the context of detecting periodic signals such as those from pulsars, involves a systematic approach to identify and extract periodic signals from noisy data. Here's a brief overview of the method: ### Concept 1. **Data Acquisition**: The method typically starts with time-series data that may include signals from various sources, such as stars or other celestial events.
