Further results on 'New fast recursive algorithms for the discrete cosine and sine transforms'

摘要

It is interesting to note that the results given in the paper of Cvetkovic and Popovic (see ibid., vol.40, no.8, p.2083, 1992) may be obtained from different derivations of previous algorithms using either forward or inverse DST/DCT. The authors discuss the discrete sine transform (DST) and discrete cosine transform (DCT) algorithms separately.
