It's not the Viterbi algorithm, but drawing a data flow diagram of one algorithm to perform thisprocess creates a butterfly shape. Bluestein developed an algorithm that can efficiently perform thisaction for prime sizes, and another method of doing it can be modified into a split‐radix versionapplicable when the input size is a multiple of four. One algorithm for performing this action splits ahighly composite number N into the product of N1 and N2 and uses complex roots of unity as (*)twiddle factors. This operation is implemented by the Cooley‐Tukey algorithm. For 10 points, name thisoperation which quickly takes a function from the time domain to the frequency domain.
