FPGA-based frequency domain using the windowed Fourier transform with the number of pieces of anti-band equalizer amplifier: This program uses high-speed FPGA, and supporting high-speed AD, DA sampling the signal, Fourier transform in the frequency domain windowing the signal operation, then the Fourier inverse transform to restore the waveform. To get the desired spectrum range.
