MATLAB Signal Processing | Fast DCT Algorithm Using FFT (Complete Code Included)
The Discrete Cosine Transform (DCT) is a special form of the Discrete Fourier Transform (DFT), where the expanded function is the Fourier transform of a real even function, consisting only of cosine terms. Its advantage lies in the fixed transformation kernel, which is beneficial for hardware implementation. Like the DFT, it possesses separability, meaning that … Read more
