This web page is dedicated to the development of the FCT as a
multipurpose signal processing and data analysis tool. The FCT was
conceived in order to detect gravity wave signals from the LIGO observatory. Since varying
frequency signals arise in many contexts, the FCT has a wide range of
applicability. We welcome and encourage all interested researchers to
download the current implementation and start applying it various data
Features The current implementation
performs a two parameter FCT on complex input data using a two
dimensional Fast Fourier Transform (FFT). The first parameter is
conjugate to the linear phase (constant frequency) term while the
second parameter is conjugate to a user specific phase function. This
phase function defines the way in which the frequency changes as a
function of the independent variable (i.e. time). In order to compile
and link the current version, you will need a C++ compiler and a
current version of FFTW, an efficient
implementation of the fast Fourier transform.
FeedbackWe encourage any and all questions, comments, and suggestions
concerning the current implementation of the FCT and this Web
