Digital filter banks and frequency division multiplex (FDM) to pulse code modulation (PCM) transmultiplexers have many applications and large efforts have been devoted to the digital implementation of these devices . We develop here a new implementation based on discrete Fourier transforms (DFTs), inverse discrete cosine transforms (IDCTs) and a nesting of DPTs and IDCTs.
