Easy is a relative term, but there is a well defined relationship between the discrete and continuous Fourier transforms. > But how do I > calculate the discrete fourier transform of a function, which fourier > transfrom I know. You can find a paper which answers your question at http://www.ecf.utoronto.ca/apsc/courses/bme595f/notes/ discretevscontinuousfouriertrans2003.pdf. Regards, Ssezi
