The principle of a new Parallel Fourier Transform (PFT) system using a differential transform matrix (DTM) is presented, and its hardware implementation is carried out. The PFT is one method which can execute a real-time Discrete Fourier Transform with low-cost parallel processing. The derivation of PFT using DTM is given. It is shown that PFT using DTM can execute the DFT by 2. 5 N digital additions or subtractions (where N is the number of input signal points) for each Fourier component. A typical experiment of the PFT is presented.
