2012TI电子设计大赛——微弱信号检测装置

微弱信号检测装置<br /> 四川理工学院&nbsp;刘鹏飞、梁天德、曾学明<br /> 摘要:<br /> 本设计以TI的Launch&nbsp;Pad为核心板,采用锁相放大技术设计并制作了一套微弱信号检测装置,用以检测在强噪声背景下已知频率微弱正弦波信号的幅度值,并在液晶屏上数字显示出所测信号相应的幅度值。实验结果显示其抗干扰能力强,测量精度高。<br /> 关键词:强噪声;微弱信号;锁相放大

MEMS麦克风有助于提高系统设计效率

A MEMS microphone IC is unique among Analog Devices, Inc., products in that its input is an acoustic pressure wave. For this reason, some specifications included in the data sheets for these parts may
