Fourier Transforms
Fourier Transform is a mathematical technique that transforms a signal from time domain to frequency domain. It decomposes a complex signal into its constituent frequencies and represents it as a sum of sine and cosine waves of different frequencies, amplitudes, and phases. Fourier Transform is widely used in signal processing, image processing, audio processing, and data compression. It helps in analyzing the frequency components of a signal and filtering out unwanted noise or interference. The inverse Fourier Transform can be used to reconstruct the original signal from its frequency components.
