The exact design methods of switched - current filters are summarized, such as the director synthesis of z - plane, euler mapping, state variable analysis, matrix decomposition, and signal - flow - graph simulation of the lc and switched capacitor prototypes. at the same time, a modified left decomposition matrix method is proposed to overcome the usual problems of large silicon area, high sensitivity and component spreads by minimizing the input circuits. examples of switched - current low - pass, high - pass and band - pass filters are given to verify the feasibility of these methods
總結分析了實現高精度開關電流濾波器設計的各種實用方法，包括z域綜合法、歐拉映射法、模擬無源lc網路和開關電容網路的狀態變量法、矩陣分解法和信號流圖轉置法，並對左分解法加以整理改進，提出一種更為簡潔的設計結構，通過減化輸入電路克服一般電路中存在的佔用矽片面積大、靈敏度高等問題。 -
It possess many of the physical properties such as high atomic number ( z ), large enough band gap, high resistivity, relatively low leakage currents, and high intrinsic mobility - lifetime ( ut ) product, which are required for room - temperature nuclear radiation detectors. so it is widely used in nuclear medical imaging system, space engineering, and astrophysics, environmental monitoring, and so on. in addition, it is the best substrate for lattice matched epitaxial growth of hg1 - xcdxte ( mct ) thin films and solar cells
用單晶czt製成的探測器可在室溫下工作，工作溫度范圍寬（ - 20 40 ） ，能量探測范圍寬（ 10kev 6mev ） ，對x射線、射線能量解析度高，在x射線、射線成像、天體物理研究、工業探測、安全檢測、核輻射探測、核廢料監控、 x射線熒光分析（ xrf ） 、 x射線斷層掃描和核醫學等方面有重要用途。 -
Their optical properties are characterized by z - can technique, uv - visible absorption spectrum and so on. the experimental results indicate that although large nonlinear refractive index is observed in two pbs / cds systems with different band gap, the sample of bigger band gap exhibit obvious nonlinear absorption in the range of nonresonance
另外，我們改變制備條件，得到了光學帶隙不同的pbs cds納米復合體系，並採用z -掃描技術研究了它們的非線性光學性質。兩個樣品都具有大的非線性折射率，但光學帶隙大的樣品在非共振區域表現出明顯的非線性吸收。 -
Scheme iii. a system combining fft algorithm with chirp - z transform to detect feedback rapidly and accurately. then, adopting a filter bank composed of 12 iir narrow - band notch filters to eliminate feedback
採用chirp - z變換（ czt ）演算法與fft演算法相結合對聲反饋進行檢測，使用由12個iir窄帶陷波器構成的濾波器組對聲反饋進行抑制。
