Inverse Fourier Transform

The Inverse Fourier Transform is a mathematical method used to convert a signal from its frequency domain back into its original time or spatial form. When we analyze a signal in terms of its frequencies, we gain insight into its different components. The inverse process reconstructs the original signal by combining these frequency components. Essentially, it translates the information from "what frequencies are present" back into "what the signal looks like in time or space," enabling us to see or analyze the original data after frequency-based analysis.
