An Inhomogeneous Uncertainty Principle for Digital Low-Pass Filters
      
This article introduces an inhomogeneous uncertainty principle for digital lowpass filters.
      
The measure for uncertainty is a product of two factors evaluating the frequency selectivity in comparison with the ideal filter and the effective length of the filter in the digital domain, respectively.

The post-deflection acceleration lens with spherical mesh grid in oscilloscope tubes are calculated with the aid of a digital computer. The paraxial behaviour of the post-deflection acceleration lens of different geometries, such as the position of the focal point, the focal length and the scan magnification, are given by numerical calculations. Several experimental tubes have been measured and the theoretical analyses are given. The results are useful for design of CRT.

Described here is a new style, cardiac pacing system—an implantable pacemaker with the programmability of parameters. It consists of a programmer and an implantable pacemaker with a digital memorial element. Whenever an adjustment is neccessary, the pacemaker can be manipulated to a new stable state with the programmer emitting a series of coded pulses toward it. The process of adjustment is quick and noninvasive.The pacemaker is made by combining a CMOS circuit with monolithic integralted circuits into a hybrid circuit, which is characterized by low dissipation, light weight and small size.

本文介绍一种新型起搏系统——参数可调的埋藏式起搏器——的设计方案及实施技术.它由一个体外操纵器及一只带有数字记忆(由CMOS电路组成)元件的埋藏式起搏器所组成.无论在起搏器埋植前或后,当需要调节参数(包括接通或关断电源)时,可使用体外操纵器向起搏器发射一组编码的磁脉冲,这组脉冲被埋藏式起搏器感受,记忆,从而控制起搏参数到一新的指定的状态,并将这种状态一直保持下去直到进行再次调节. 由CMOS电路及混合型集成电路组成的起搏器具有功耗低、体积小、重量轻的特点.十个月的临床应用表明:调节灵活,性能可靠,疗效良好.

The Max.sensitivity of D.C. digital Voltmeter reached present in our countvy is 0.1μV. In compares with the advance level of world, it is about two orders of megnitude lagging. In order to raise the sensitivity by one order of magnitude. We have devoloped the 10nv amplifier. This paper introduces. the principle of the 10nv amplifier, The MOS—FET chopper is analysed in detail. According to the noise theory, the determinations of source risestance and active component of first stage, and selection of operating point are discussed. The "fast speed circuit" are applied for compromising the contradiction between Sensitivity and band pass. Finally, We deal with to technique requirements of the low noise circuit.

目前,国内生产的直流数字电压表,其最高灵敏度为0.1μV,距世界先进水平相差两个量级,为了把该项指标再提一个量级,我们研制了十毫微伏放大器。文中介绍了该放大器的原理,对MOS—FET斩波器进行了详细的分析。并从噪声理论出发,讨论了信号源阻抗,前级有源器件及工作点的选取;且引入“快速电路”较好地解决了通频带和灵敏度的矛盾,最后阐明了低噪电路的工艺要求。
