Cóip statach de shonraí a easpórtáiltear ó IATE ó am go chéile atá sa chnuasach seo. Níor cheart glacadh leis gurb ionann i gcónaí an t-eolas a thugtar faoi iontráil anseo agus a bhfuil sa leagan reatha den iontráil ar IATE. Is féidir an leagan reatha sin a cheadú ach cliceáil ar an nasc atá ar thaobh na láimhe deise ag barr gach iontrála. Breis eolais »

    Sainmhíniú mathematical algorithm widely used in science and engineering that converts a signal which is intensity vs time into a spectrum which is amplitude vs frequency, and the latter is actually a complex spectrum where for each frequency both the phase & amplitude is specified Tagairt "Externally Dispersed Interferometry, Lawrence Livermore National Laboratory and Space Science Lab. UC Berkeley. EDI Glossary > Fourier Transform. http://www.spectralfringe.org/EDI/terminology.html [27.6.2013]"
    Nóta There is an associated inverse Fourier transform that converts the complex spectrum back into a time dependent signal.
