| Abstract: | Digtal Down Converter technology is the core technology of software-defined radio, which is an important foundation for digital receivers. This thesis introduces briefly the principle of DDC and the internal structure and powerful function of ISL5216. Key technologies of using ISL5216 to realize the design of DDC in HF 2-channel Receiver are mainly illustrated. And the design methods of the Decimation filter and the Shaping filter which are used for extracting Narrow-band digital signal from Broadband IF are discussed emphatically. The experiment results are given. |
