Abstract
A realization for the discrete cosine and sine transforms (DCT and DST) is proposed which is based on an FFT (fast Fourier transform) optimized for DSP (digital signal processor) use. Besides its regular structure, even the theoretically interesting total number of required operations is about the same as needed by the most regular direct approach and only slightly higher than the minimum number yet published. Compared to a similar approach published recently by N. Ramamurthy and M.N.S. Swamy (1990), it is even more efficient
