The radix-2 algorithm is an efficient method for computing the Discrete Fourier Transform (DFT) by recursively breaking down a DFT of size N into smaller DFTs of size N/2. This algorithm is particularly significant because it reduces the computational complexity from O(N^2) to O(N log N), making it much faster for large datasets. By utilizing properties of symmetry and periodicity, this method simplifies calculations, allowing for quicker processing in signal analysis and processing applications.
