ddc digital data converter 中文意思是什麼
ddc digital data converter
解釋
數字數據轉換器-
Digital down converter ( ddc ) converts digitized if data into filtered baseband data which can be processed by a standard dsp microprocessor. ddc is a core part of a software defined radio ( sdr ) system
數字下變頻( ddc : digitaldownconvert )是將中頻信號數字下變頻至零中頻且使信號速率降至適宜通用dsp器件處理速率的技術。 -
Digital down - converter ( ddc ) is one of the key technologies used by sdr receiver. the ddc module is a data processing part, following the ad sampler. the main function of ddc is extracting narrow - band data from broad - band data which is digitalized by ad sampler, down - converting these data to base - band, and decreasing data rate as well
Ddc數字下變頻器技術作為軟體無線電中的核心技術,是緊跟在ad采樣后的一個處理模塊,他的主要功能是從輸入的寬帶高速數字信號中提取所需的窄帶信號,將其下變頻為數字零中頻,並降低數據的速率。
