摘要：图1所示为一个典型的嵌入式系统，包含有微处理器、外围接口、内存、电源等主要部件。微处理器上有多种串行总线信号，如CAN、UART、LIN、SPI、I^2C等，不同总线有不同的用途，如CAN信号主要用于微处理器与微处理器之间进行互连，I^2C、SPI等信号主要用于微处理器与外网接口进行互连。

摘要：Anodic urea oxidation reaction(UOR)is an intriguing half reaction that can replace oxygen evolution reaction(OER)and work together with hydrogen evolution reaction(HER)toward simultaneous hydrogen fuel generation and urea-rich wastewater purification;however,it remains a challenge to achieve overall urea electrolysis with high ***,we report a multifunctional electrocatalyst termed as Rh/Ni V-LDH,through integration of nickel-vanadium layered double hydroxide(LDH)with rhodium single-atom catalyst(SAC),to achieve this *** electrocatalyst delivers high HER mass activity of0.262 A mg^(-1) and exceptionally high turnover frequency(TOF)of 2.125 s^(-1) at an overpotential of100 m ***,exceptional activity toward urea oxidation is addressed,which requires a potential of 1.33 V to yield 10 mA cm^(-2),endorsing the potential to surmount the sluggish *** splendid catalytic activity is enabled by the synergy of the Ni V-LDH support and the atomically dispersed Rh sites(located on the Ni-V hollow sites)as evidenced both experimentally and *** selfsupported Rh/Ni V-LDH catalyst serving as the anode and cathode for overall urea electrolysis(1 mol L^(-1) KOH with 0.33 mol L^(-1) urea as electrolyte)only requires a small voltage of 1.47 V to deliver 100 mA cm^(-2) with excellent *** work provides important insights into multifunctional SAC design from the perspective of support sites toward overall electrolysis applications.

摘要：1引言模拟工程师和数字工程师在谈及波形测量时会有不同的需求，而且不得不选择不同的示波器来优化各自的任务。数字系统工程师往往侧重于示波器的采样率、存储深度、带宽、先进触发类型以及分析功能，然而分辨率、精度、噪声以及无杂散动态范围（SFDR）是验证设计中使用的模拟元件的关键指标。
