ADC转换器技术用语 (A/D Converter Defi
ANALOG INPUT BANDWIDTH is a measure of the frequency<BR>at which the reconstructed output fundamental drops<BR>3 dB below its low frequency value for a full scale input. The<BR>test is performed with
WP276 -可编程的开发和测试
<div>
We all know the benefits of using FieldProgrammable Gate Arrays (FPGAs): no NRE, nominimum order quantities, and faster time-tomarket.In an ideal world, designs would never needto be changed be
LS7266R1在电子式万能材料试验机中的应用
针对材料试验机等设备中要求测量或控制材料拉伸或压缩的位移，一般采用光电轴角编码器检测位置信号，输出正交编码脉冲信号。若采用其他方法检测位置信号，必然导致电路设计复杂，可靠性降低。因此，提出一种基于LS7266R1的电子式万能材料试验机设计方案。给出了试验机中的控制器工作原理，LS7266R1与单片机的接口硬件设计，以及主程序软件流程图。巧妙地把力量传感器，位移传感器等机械运动状态的压力或拉力以及位

This application note describes how to build a system that can be used for determining theoptimal phase shift for a Double Data Rate (DDR) memory feedback clock. In this system, theDDR memory i
基于IC卡的新型供暖计费系统设计
将现行的供暖计费方式由按建筑面积计费变为按消耗的热能计费是供暖计费方式发展趋势，为了满足这一计费方式变化的需要，设计了基于IC卡的预付费式新型供暖计费系统，通过测量用户采暖系统进出口的温度和流量，计算用户消耗的热能，利用IC卡记录用户预付费的金额和当年热能的单价，根据热能消耗和当年热能的单价计算用户采暖费，根据实际发生的供暖费用和预付费金额控制供暖的开停，这一计费方式的变化使供暖计费更趋合理。
