  • 测量和控制的实用电路分析

      This collection of circuits was worked out between June1991 and July of 1994. Most were designed at customerrequest or are derivatives of such efforts. All representsubstantial effort and, as such, are disseminated here forwider study and (hopefully) use.1 The examples areroughly arranged ...

  • Wide-input dc/dc modules offer

    When a system designer specifies a nonisolated dc/dc powermodule, considering the needed input voltage range isequally as important as considering the required performanceattributes and features. Generally, nonisolated moduleshave either a narrow or a wide input voltage range. Narrowinputmodules typ ...

  • 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, ...

  • X-tal oscillators on 8-bit mic

    <Almost since the introduction of microcontrollers as electronic components there always has been an oscillatorcircuit on the device to make it work. From application point of view only some external components wererequired to make it work. However, to make sure that it will always work required mor ...

  • Input Signal Rise and Fall Tim

    All inputs of the C16x family have Schmitt-Trigger input characteristics. These Schmitt-Triggers are intended to always provide proper internal low and high levels, even if anundefined voltage level (between TTL-VIL and TTL-VIH) is externally applied to the pin.The hysteresis of these inputs, howeve ...

  • 状态机学习心得

      FSM 分两大类:米里型和摩尔型。   组成要素有输入(包括复位),状态(包括当前状态的操作),状态转移条件,状态的输出条件。   设计FSM 的方法和技巧多种多样,但是总结起来有两大类:第一种,将状态转移和状态的操作和判断等写到一个模块(process、block)中。另一种是将状态转移单独写成一个模块,将状态的操作和判 ...
