Like the Fourier transform a constant Q transform is a bank of 57356lters but in contrast to the former it has geometrically spaced center frequencies 0 where dictates the number of 57356lters per octave To make the 57356lter domains adjectant one Madan In this paper the authors show how the fast Fourier transform may be used to value options when the characteristic function of the return is known analytically 1 INTRODUCTION The Black57521Scholes model and its extensions comprise one of the m Fourier Series Vs.
