  1. Due to the hardware characteristic ' s limitation, such as the poor speed of a / d, d / a conversion and dsp process, the most part of sr system adopt middle course. that is to say, by using the special digital converter or running relevant arithmetic, it converts the radio signal to intermediate frequency signal and completes the base - band signal process that is n ' t the veriest sr and is named " software defined radio ( sdr ) "

    由於受到硬體性能如a d 、 d a及dsp處理速度的限制,目前的軟體電系統多採折中的實現方案,增加的數字變頻器或者運行數字變頻演算法,將射頻信號變頻到中頻,然後再進行基帶信號處理,這樣的軟體電系統又被稱之為「軟體定義電」 ,它並不是真正意義上的軟體電。
  2. + then it will do some other digital process. the evolution of programmable hardware and increased flexibility via increased programmability has been accomplished by a combination of techniques

    實現軟體電技術的關鍵技術包括高速a d及高速的可編程數字處理器等,目前的軟體電系統多採處理與dsp相結合的方法。
  3. Wireless special - purpose chip

    無線專用晶元
  4. Based on the analysis, we bring up a new way of thinking, after considering the characteristics of the dds design in software radio system platform. we adopt the rom compression technique of dds special chip and other optimizing methods in the design. we still bring up a new modified method, of which the compression ratio is 139. 6 : 1

    在此理論分析基礎上,針對在軟體電平臺中的直接數字頻率合成設計特點,對dds進行分析后提出新思路,將dds中所使的幅度表壓縮技術於軟體電平臺中的dds設計,同時採其它輔助方法進行了優化設計,並提出一種新的改進方法,將壓縮比提高到139 . 6 : 1 ,很好的改進了軟體電平臺中直接數字頻率合成的雜散抑制性能。
  5. Quart crystal devices and materials, sensors and materials, resistors, potentiometers, capacitors and ti - srseries ceramics powder, high performance electronic ceramic material and parts, industry furnaces, various electric instruments and specific equipment

    主要產品:石英體材料和器件,敏感材料和器件,電阻器,電容器及鈦鍶系統瓷粉,高性能電子陶瓷材料及結構件,工業窯爐,電測試儀器和設備。
  6. Shenzhen luguang electronic technology co., ltd is a high - new electronic technical enterprise, which is specializing in r & d, manufacturing, and selling of various piezoelectric materials, such as piezoelectric frequency components, diodes, transistors, digital television receiver, wireless controller, etc
