Order tracking (signal processing)

In signal processing, "order tracking" refers to a technique used to analyze and understand the behavior of systems or processes, particularly in the context of rotating machinery or systems with periodic or quasi-periodic signals. The primary goal of order tracking is to extract meaningful information from signals that are related to specific rotational or operational speeds. ### Key Concepts 1. **Orders**: In the context of rotating systems, an "order" refers to a harmonic of the fundamental frequency.
