测试测量 XAPP713 -Virtex-4 RocketIO误码率测试器
 
The data plane of the reference design consists of a configurable multi-channel XBERT modulethat generates and checks high-speed serial data transmitted and received by the MGTs. Eachchannel in the XBERT module consists of two MGTs (MGTA and MGTB), which physicallyoccupy one MGT tile in t ...
测试测量 ADC简化测量高阻抗传感器
 
Delta-sigma ADCs, with their high accuracy and high noiseimmunity, are ideal for directly measuring many typesof sensors. Nevertheless, input sampling currents canoverwhelm high source impedances or low-bandwidth,micropower signal conditioning circuits. The LTC®2484family of delta sig ...
测试测量 LT5514三阶互调的精确测量
 
Accurate measurement of the third order intercept pointfor low distortion IC products such as the LT5514 requirescertain precautions to be observed in the test setup andtesting procedure. The LT5514 linearity performance ishigh enough to push the test equipment and test set-up totheir lim ...
测试测量 低噪声电压基准的噪声测量
 
Frequently, voltage reference stability and noise defi nemeasurement limits in instrumentation systems. In particular,reference noise often sets stable resolution limits.Reference voltages have decreased with the continuingdrop in system power supply voltages, making referencenoise increa ...
测试测量 基于MASON公式的多功能二阶通用滤波器设计
基于通用集成运算放大器，利用MASON公式设计了一个多功能二阶通用滤波器，能同时或分别实现低通、高通和带通滤波，也能设计成一个正交振荡器。电路的极点频率和品质因数能够独立、精确地调节。电路使用4个集成运放、2个电容和11个电阻，所有集成运放的反相端虚地。利用计算机仿真电路的通用滤波功能、极点频率和品质因数的 ...
设计相关 Arduino应用_Arduino连接超声波传感器测距
超声波传感器适用于对大幅的平面进行静止测距。普通的超声波传感器测距范围大概是 2cm~450cm，分辨率3mm（淘宝卖家说的，笔者测试环境没那么好，个人实测比较稳定的 距离10cm~2m 左右，超过此距离就经常有偶然不准确的情况发生了，当然不排除笔者技术 问题。）
测试对象是淘宝上面最便宜的SRF-04 超声波传感器，有四个脚 ...
设计相关 Arduino学习笔记4_Arduino软件模拟PWM
注:1.这篇文章断断续续写了很久,画图技术也不精,难免错漏,大家凑合看.有问题可以留言.
     2.论坛排版把我的代码缩进全弄没了,大家将代码粘贴到arduino编译器,然后按ctrl+T重新格式化代码格式即可看的舒服.
一、什么是PWM
PWM 即Pulse Wavelength Modulation 脉宽调制波，通过调整输出信号占空 ...
