諧振器論文精選.rar

Control systems are becoming increasingly dependent on digital processing and so require sensors able to provide direct digital inputs. Sensors based on time measurement, having outputs based on a frequency or phase, have an advantage over conventional analogue sensors in that their outputs can be measured directly in digital systems by pulse counting.

CTP知識全解

　　1.什么是CTP? 　　CTP包括幾種含義: 　　脫機直接制版(Computer-to-plate) 　　在機直接制版(Computer-to-press) 　　直接印刷(Computer-to-paper/print) 　　數字打樣(Computer-to-proof) 　　普通PS版直接制版技術,即CTcP(Computer-to-conventional plate) 　　這里所論述的CTP系統是脫機直接制版(Computer-to-plate)。CTP就是計算機直接到印版，是一種數字化印版成像過程。CTP直接制版機與照排機結構原理相仿。起制版設備均是用計算機直接控制，用激光掃描成像，再通過顯影、定影生成直接可上機印刷的印版。計算機直接制版是采用數字化工作流程，直接將文字、圖象轉變為數字，直接生成印版，省去了膠片這一材料、人工拼版的過程、半自動或全自動曬版工序。

降壓升壓型控制器簡化手持式產品的DC/DC轉換器設計

A number of conventional solutions have been available forthe design of a DC/DC converter where the output voltageis within the input voltage range—a common scenarioin Li-Ion battery-powered applications—but none werevery attractive until now. conventional topologies, suchas SEPIC or boost followed by buck, have numerousdisadvantages, including low effi ciency, complex magnetics,polarity inversion and/or circuit complexity/cost. TheLTC®3785 buck-boost controller yields a simple, effi cient,low parts-count, single-converter solution that is easyto implement, thus avoiding the drawbacks associatedwith traditional solutions.
