Answer / Subodh Shukla

The Fourier transform is a mathematical technique used to decompose a signal or function from the time domain into the frequency domain. It provides an alternative representation of a signal in terms of its constituent frequencies and their amplitudes, which can be useful for analyzing signals such as sound waves, images, and electrical signals. The Fourier transform helps identify patterns, localize frequencies, filter noise, and perform other signal processing tasks.
