例句与用法

  • For low distortion , the drains ( or collectors ) of a differential amp " s front - end should be bootstrapped to the source ( or emitter ) so that the voltages on the part are not modulated by the input signal
    为了得到低失真，差分放大器前端的漏极（或集电极）应该被引导到源极（或射极） ，这样端口电压就不会被输入信号调制了。
  • After pin ’ s noise and equivalent circuit are discussed , this thesis introduces technology and methods of signal management , including pre - amplifier and differential - amplifier , bpf , lia , etc . at the end of paper , the system of photoacoustic spectrometer is proved by experiment
    本文在讨论了光电二极管的噪声和等效电路之后，介绍了信号处理的技术和方法，包括前置放大器、差分放大器和有源带通滤波器的设计及用于微弱信号检测的锁相放大技术。
  • Two wedge interferometers are designed that the thickness of one is higher than the other . so when the incident coherent light through the interferometers can acquire two fringe patterns which having space shift , but the incident incoherent light only result in consistent intensity signal . through a differentiating amplifier , two signals subtract which can eliminate noise of background and result in higher contrast ratio fringe signals . this method largely improves the system and the ability of detection . the spacing of line fringes is a function of incident laser wavelength , by analyzing , we can extract the wavelength of incident laser . the optical unit analyzing and results also simulated with matlab
    当背景光入射时，直接穿过干涉仪，仅发生强度的衰减，在两个探测平面上产生幅度基本一致的灰度信号，通过差分放大器，相消为零，从而抑制了背景干扰。当激光信号入射，穿过干涉仪时受到调制，在探测平面上产生干涉条纹。通过所设计的存在平均厚度差的双楔形干涉仪，两路干涉条纹图案出现相对移位：在两个探测平面对应的位置上，一路出现亮纹，另一路出现暗纹。
  • In the paper a gmc filter with a cutoff frequency of 29 . 8mhz is implemented . an effective improvement is made in cmfb ( common mode feedback ) through using a differential amplifier with four inputs . transconductors are tuned through comparing two voltages , which helps to stabilize the cutoff frequency
    文中实现了跨导电容滤波器，其截止频率达到29 . 8mhz ；采用四输入端的差分放大器使共模反馈得到了有效的改善；通过简单的电压比较实现跨导器的调谐，有助于稳定截止频率。
