I N-PLACE , IN-ORDER MI XED- RADIX FFTs

Conditions are stated for mixed-radix FFTs that are both in-place and in-order. ordering of both the input and output data is achieved as the computation progresses at the expense of a small amount of temporary storage. The number of additional data transfers is the order of 1 L/2lN where N has L factors, but the logic for the data transfers is very simple. The natural
