摘要：
Through the theory of Digital Down-Conversion, the paper brings forward the proposal that rising multi-stage filtering and decimation to reduce the amount of computation and memory space, and targeted solved the technical question of spectrum aliasing. Combination of an engineering practice designed by Inlet-mediate Frequency Digital Demodulator, the paper suggests an optimal configuration principle and method to the programmable Digital Down-Convener HSP50214B, making the demodulator achieves a very good receiving and demodulation effect.
