  1. Signal which prevents accidental operation by spurious signals or avoids possible ambiguity

    防止假信號的意外作用或者避免二義性而設置的信號。
  2. Direct modulator converts baseband signal to rf signal without upconvertion. the system design is relatively simple compared to upconversion. so direct modulator provides adventages of compact size, low cost and low spurious response

    直接調制將基帶信號直接轉換為射頻信號，不需要二次頻率變換，與上變頻方式相比系統結構簡單，降低了對濾波器的要求，具有體積小，重量輕，成本低等明顯的優點。
  3. Aiming at the scheme of the signal electromagnetic environment simulator of the wireless communication system, the mission of this project is to design and realize twenty - four frequency synthesizers, which must meet high expectation for the phase noise characteristic and the spurious repression characteristic of the output clock signal. these frequency synthesizers provide the moving of the basic signal generating modules to radio frequency with stable inspiring source

    本課題的任務是針對通信信號電磁環境模擬器系統的方案要求，設計實現24個（頻率分佈在260mhz 1430mhz之間）對輸出時鐘信號的相位噪聲特性、雜散抑制特性等要求都很高的頻率合成器，為基本信號生成模塊到射頻的搬移提供穩定可靠的激勵源。
  4. In pulse code modulation, a spurious signal formed from beats between the signal frequency and the sample frequency

    在脈沖編碼調制中，信號頻率和取樣頻率之間的差拍所引起的偽信號。
  5. What ' s more, some problems that should be pay attention to the design of dds / pll signal generator are analyzed particularly. the author clarifies the distributions of spurious frequency and the suppressing for output spurs in dds in this section

    然後深入分析了dds / pll信號發生器設計中應注意的問題，其中特別對dds的雜散分佈和抑制提出了一些見解。
