  1. The amplitude discrimination circuit, the filter circuit and the amplifying circuit are designed to transform ac analog signal that the eddy current sensor output to dc analog signal, thus, the dc analog signal can be received by ad converter

    傳感器輸出的測量信號是中頻的交流模擬信號，在下位機系統設計了鑒幅、濾波、放大電路將測量信號轉化為模數轉換器可以接受的直流信號。
  2. By using msp430 micro controller unit and cpld technology, this method realized twofold frequency phase ranging : the rough measurement of the distance is realized by countering high frequency pulses which are filled in discriminating phase pulses ; the accurate discriminating phase pulses are converted by using the method of time to voltage conversion, and then the adc device samples the converted voltage, so the accurate measurement of the distance is obtained by processing the adc samples through micro controller unit

    該方法通過msp430單片機和先進的cpld技術實現雙頻測相:粗測通過採用對鑒相脈沖填充高頻脈沖的辦法來實現;精測則利用時間-電壓轉換法對鑒相脈沖進行轉換，然後由模數轉換器adc對轉換電壓進行采樣，通過單片機對adc的輸出值進行計算處理獲得精測值。
  3. This subject aim at designing a linear power amplifer whose output power is 40w for 225 - 450mhz band. but it seems not easy to finish the task because of this power amplifier own unique requirements including high output power, broad working frequency band, high linearity, and flat gain. due to the complexity involved, theoretically several soltuions are derived in the final scheme such as broadband matching technology, power - retreat, power synthesize, automatic power control and negative feedback. in addition, the design will be optimized by eda software and the final test result indicates that our design is successful

    本課題的目標是研製一個輸出功率為40w的225 450mhz的線性功率放大器。由於該功放要求輸出功率大，工作頻帶寬，帶內增益波動小，線性度高，所以其終合設計難度大。鑒于這個原因，在理論設計上筆者採用了寬帶匹配、功率合成、功率回退、負反饋、自動功率控制等技術；在實踐中精心設計電路，並且配合eda軟體模擬，最終達到所要求的指標。
  4. Due to the multi - carrier transmission technology used in mc - cdma systems, almost all the previous synchronization algorithms in mc - cdma systems are derives from that in ofdm systems. they are suitable for ofdm systems, but they are not optimal for mc - cdma systems. the data symbols transmitted in mc - cdma systems have form of cdma signal, which is greatly different from normal binary signal

    傳統的各種mc - cdma同步演算法主要還是借鑒了ofdm的同步演算法，本文提出採用用戶擴頻碼作idft后在fft之前作同步，充分利用了ofdm信號中所包含的mc - cdma信號形式，它與純粹的ofdm傳輸的二進制數據不同，它與pn序列具有更好的相關性。
  5. But its performance is as same as common pll at a 5v voltage. so the pll performance is better than other plls at a 5v voltage, especially in power consumption and frequency. finally, the improved pll circuit used in the frequency synthesizer is composed of the improved vco, phase / frequency detector and charge pump. hspice simulation results show that the pll performance is better than other plls implemented by other vco in the same cmos technology

    綜合以上的研究與設計，本文用所改進的壓控振蕩器、無死區鑒相器及電荷泵電路組成了用於頻率合成的鎖相環電路，並對此電路進行整體設計及模擬，結果表明其在鎖定時間、頻率范圍、輸出相位抖動及功耗方面具有較好的性能，且對提高鎖相環頻率合成器的整體性能有一定的作用。
  6. Especially at millimeter - wave frequencies, power available from each monolithic microwave integrated circuit ( mmic ) is limited, and subsequent power combining is required to achieve the desired output power

    特別是在毫米波頻段，鑒于單個單片集成電路可能提供的功率有限，要提高系統的輸出功率就需要採用功率合成技術。
  7. With the application of phase detector in industrial experiment on the spot, when the phase of working frequency power supply is consistent with the output phase of variable frequency power supply, plc sends out the instruction to switch off the output of transducer. the electromotor is connected with the industrial frequency voltage after it was disconnected from the out

    在現場工業試驗引入鑒頻鑒相控制器，在工頻電源和變頻輸出電源相位一致時， plc發出指令切斷變頻器輸出，電機從變頻器輸出端斷開后，馬上接入工頻電源，轉換時間控制在幾十毫秒之內。
