Spectral estimation

Spectral estimation is a method used to analyze signals or data to identify the different frequencies that make them up. Imagine listening to a complex sound and wanting to know what musical notes or tones are present. Similarly, spectral estimation helps determine the specific frequencies within signals like audio, electricity, or communication signals. It transforms the data from its original form into a frequency-based view, revealing patterns or components that might not be obvious in the time domain. This process is essential in various fields, including engineering, medicine, and science, to understand the underlying structure of complex signals.
