  • This C++ code example demonstrates how to localise an application to adapt to the Selected phone lan

    This C++ code example demonstrates how to localise an application to adapt to the Selected phone language. The example application has two sets of localised strings (English and German) for the application name, labels, text, and image. The application also includes number, currency, date, and time localisation, in which the TLocale method is used for localisation even if the Selected phone language is neither one of the two application languages. The updated example has been tested to support S60 5th Edition and touch UI.

  • 相敏检波电路鉴相特性的仿真研究

    分析了调幅信号和载波信号之间的相位差与调制信号的极性的对应关系,得出了相敏检波电路输出电压的极性与调制信号的极性有对应关系的结论。为了验证相敏检波电路的这一特性,给出3 个电路方案,分别选用理想元件和实际元件,采用Multisim 对其进行仿真实验,直观形象地演示了相敏检波电路的鉴相特性,是传统的实际操作实验所不可比拟的。关键词:相敏检波;鉴相特性;Multisim;电路仿真 Abstract : The corresponding relation between modulation signal polarity and difference phases of amplitudemodulated signal and the carrier signal ,the polarity of phase2sensitive detecting circuit output voltage and the polarity of modulation signal are correspondent . In order to verify this characteristic ,three elect ric circuit s plans are produced ,idea element s and actual element s are Selected respectively. Using Multisim to carry on a simulation experiment ,and then demonst rating the phase detecting characteristic of the phase sensitive circuit vividly and directly. Which is t raditional practical experience cannot be com pared.Keywords :phase sensitive detection ;phase2detecting characteristic ;Multisim;circuit simulation

  • 100-15V TO 12V DCDC 原理图 PCB BOM表

    高的工作电压高达100V N双N沟道MOSFET同步驱动 The D810DCDC is a synchronous step-down switching regulator controller that can directly step-down voltages from up to 100V, making it ideal for telecom and automotive applications. The D810DCDC uses a constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit, without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifi er provides very fast line and load transient response. Large 1Ω gate drivers allow the D810DCDC to drive multiple MOSFETs for higher current applications. The operating frequency is Selected by an external resistor and is compensated for variations in VIN and can also be synchronized to an external clock for switching-noise sensitive applications. Integrated bias control generates gate drive power from the input supply during start-up and when an output shortcircuit occurs, with the addition of a small external SOT23 MOSFET. When in regulation, power is derived from the output for higher effi ciency.
