Frequency Domain

The frequency domain is a way of analyzing signals or data by breaking them down into their basic components based on how often they repeat over time or space. Instead of looking at the signal as a whole, it shows which frequencies—such as slow changes or rapid fluctuations—are present and how strong they are. This approach helps us understand the underlying patterns and characteristics of the data, making it easier to identify specific features like noise, periodic signals, or dominant patterns. It's commonly used in fields like audio processing, communications, and engineering for detailed analysis and filtering.
