frequency domain analysis

Frequency-Domain Analysis is a method used to examine how various frequency components make up a signal, such as sound or light. Instead of looking at how a signal changes over time, this approach breaks it down into its individual frequencies. Think of it like taking a music track and identifying its different notes and rhythms. This analysis helps in understanding, filtering, or processing signals, as it makes clear which frequencies are present and how strong they are. It's widely used in fields such as acoustics, telecommunications, and image processing for better interpretation and manipulation of data.
