| Abstract: | This paper puts forward the design method of DTV transposer using baseband demodulator as its core based on the analysis of its present status. At first the article puts forward the scheme for system design, then introduces the design of baseband demodulator with AD6652 and the main features of AD6652, and gets the experimental spectrum at the end. Experimental results show that the design completely meets the requirements of practical application in the field of DTV and has good performance and prospect. |
