Any Band-Pass filter may be converted into a tunable filter with a single tuning parameter through the use of a new Tunable Heterodyne Band-Pass Filter concept in which the frequency of the heterodyne signal is adjusted thereby translating the

关于DFT的文章，应用FPGA实现傅立叶变换。-Abstract—We present a domain-specific approach to generate high-performance hardware-software partitioned implementations of the discrete Fourier transform (DFT). The partitioning strategy is a heuristic based on the DFT
