  2. Very high frequency direction - finding

    甚高頻測向
  3. Abstract : to obtain the high frequency ( hf ) array signals, an applied circuit called hf array signals generator is designed using dsp and duc ( digital up converter ). the generator simulates the generation of output signals of 9 - element arrays with different array format, different direction of arrival ( doa ) and existing cochannel signals respectively

    為了在實驗室中獲得短波天線陣列信號,應用dsp晶元和duc晶元(數字上變頻器)設計了一個實用電路短波陣列信號發生器,模擬實現了短波九元天線陣的多種陣型、不同來波方向及存在同頻多信號時的陣列輸出信號。
  4. Since the cause of caustics phenomena is that the tangent plane of lagrange submanifold in caustic fields is perpendicular to the original physical space, we solve the high frequency asymptotic problem in a new mixed space by changing the projecting direction, then we get the high frequency asymptotic solutions of wave equations efficiently near and on the caustics

    由於出現焦散現象的原因在於lagrange子流形在該處的切平面與物理空間垂直,通過轉換適當的投影方向,然後將這個投影方向上得到的高頻近似解再變換回到原來的物理空間中,得到了在焦散附近適用的高頻近似解。
  5. Continuous - time analog filter is the only method when processing high frequency signal ( usually above 1mhz ) in low power consumption. it has been widely used in the area of communication, electronic measurement, instruments, autocontrol, etc. it ’ s especially used in digital and analog mixed signal processing and communication integrated circuit. current - mode filter becomes the new research direction in the world, as it ’ s high speed, low power consumption and simple configuration

    提出了基於ota的多功能電流模式雙二階濾波器,基於ota的八階切比雪夫濾波器,用模擬lc梯形電路法設計橢圓低通濾波器時,在傳統的狀態變量選取方法的基礎上,用改進后的狀態變量選取方法得到了( k + 1 )階橢圓函數低通濾波器的簡化信號流圖,實現了簡化的基於ota的橢圓低通濾波器電路。
