Abstract :
Through the theory of Digital Down-Conversion, the paper brings forward the proposal that using 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 Intermediate Frequency Digital Demodulator, the paper suggests an optimal configuration principle and method to the programmable Digital Down-Converter HSP50214B, making the demodulator achieves a very good receiving and demodulation effect.
