"WebFFT can be used instead of a radix-2 FFT. With a radix-4 the computational complexity is reduced, i.e. the number of complex multiplications is reduced compared to a radix-2 FFT. The drawback with a radix-4 is that the butterfly structure is more complicated. Another, better type of radix-4 is the radix-22, there the butterflies still " - Difference between radix 2 and radix 4

WebJan 18, 2014 · In this case we mean the numeric base, and we'll consider storing binary data. Radix R = 2 ^ x, where x >= 1. Take the example of a binary (2-ary) trie. The radix is 2, so at each node you can compare one bit. The two children will handle all of the possible outcomes: the bit is 0; the bit is 1; The next level of complexity would be a 4-ary trie.
