The “bottom-line” metrics of cash flow, demand, price, and return on investment are driven by a second set of financial metrics represented by value to the customer, cost, and the pace of innovation. Get them right relative to competition and impressive bottom-line results should follow. Because of their importance, we call value to the customer, variable cost, and the pace of innovation the “fundamental metrics.”

微弱信号检测装置 四川理工学院 刘鹏飞、梁天德、曾学明 摘要: 本设计以TI的Launch 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。 关键词:强噪声;微弱信号;锁相放大;Launch Pad Abstract: This design is based on the Launch Pad of TI core board, using a lock-in amplifier technique designed and produced a weak signal detection device, to measure the known frequency sine wave signal amplitude values of the weak in the high noise background, and shows the measured signal amplitude of the corresponding value in the liquid crystal screen. Test results showed that it has high accuracy and strong anti-jamming capability. Keywords: weak signal detection; lock-in-amplifier; Launch Pad 1、引言 随着现代科学技术的发展,在科研与生产过程中人们越来越需要从复杂高强度的噪声中检测出有用的微弱信号,因此对微弱信号的检测成为当前科研的热点。微弱信号并不意味着信号幅度小,而是指被噪声淹没的信号,“微弱”也仅是相对于噪声而言的。只有在有效抑制噪声的条件下有选择的放大微弱信号的幅度,才能提取出有用信号。微弱信号检测技术的应用相当广泛,在生物医学、光学、电学、材料科学等相关领域显得愈发重要。 2、方案论证 针对微弱信号的检测的方法有很多,比如滤波法、取样积分器、锁相放大器等。下面就针对这几种方法做一简要说明。 方案一:滤波法。 在大部分的检测仪器中都要用到滤波方法对模拟信号进行一定的处理,例如隔离直流分量,改善信号波形,防止离散化时的波形混叠,克服噪声的不利影响,提高信噪比等。常用的噪声滤波器有:带通、带阻、高通、低通等。但是滤波方法检测信号不能用于信号频谱与噪声频谱重叠的情况,有其局限性。虽然可以对滤波器的通频带进行调节,但其噪声抑制能力有限,同时其准确性与稳定性将大打折扣。
