Abstract :
The commenter states that, because of the use of Farey sequences the result stated by N. Tepedelenlioglu (ibid., vol.37, no.7, p.1146-7, 1989) becomes a statement about D/sub N/, the number of elements in a Farey sequence of order N. Tepedelenlioglu´s formula is then equivalent to a formula about Farey sequences given by M.R. Schroder (1986) C.M. Rader (1977). Thus, for example, while a standard FTT algorithm requires 1024 samples to yield 1024 spectral components, AFT would take more than 300000 samples to do the same job.<>
