PCB線寬和電流關系公式 先計算Track的截面積,大部分PCB的銅箔厚度為35um(即 1oz)它乘上線寬就是截面積,注意換算成平方毫米。 有一個電流密度經驗值,為15~25安培/平方毫米。把它稱上截面積就得到通流容量。 I=KT(0.44)A(0.75), 括號里面是指數, K為修正系數,一般覆銅線在內層時取0.024,在外層時取0.048 T為最大溫升,單位為攝氏度(銅的熔點是1060℃) A為覆銅截面積,單位為Square mil. I為容許的最大電流,單位為安培。 一般 10mil=0.010inch=0.254mm 1A , 250mil=6.35mm 8.3A ?倍數關系,與公式不符 ?

鎖定放大是微弱信號檢測的重要手段。基于相關檢測理論,利用開關電容的開關實現鎖定放大器中乘法器的功能,提出開關電容和積分器相結合以實現相關檢測的方法,并設計出一種鎖定放大器。該鎖定放大器將微弱信號轉化為與之相關的方波,通過后續電路得到正比于被測信號的直流電平,為后續采集處理提供方便。測量數據表明鎖定放大器前級可將10-6 A的電流轉換為10-1 V的電壓,后級通過帶通濾波器級聯可將信號放大1×105倍。該方法在降低噪聲的同時,可對微弱信號進行放大,線性度較高、穩定性較好。 Abstract: Lock-in Amplifying(LIA)is one of important means for weak signal detection. Based on cross-correlation detection theory, switch in the swithched capacitor was used as multiplier of LIA, and a new method of correlation detection was proposed combining swithched capacitor with integrator. A kind of LIA was designed which can convert the weak signal to Square-wave, then DC proportional to measured signal was obtained through follow-up conditioning circuit, providing convenience for signal acquisition and processing. The measured data shows that the electric current(10-6 A) can be changed into voltage(10-1 V) by LIA, and the signal is magnified 1×105 times by cascade band-pass filter. The noise is suppressed and the weak signal is amplified. It has the advantages of good linearity and stability.

6小時學會labview, labview Six Hour Course – Instructor Notes This zip file contains material designed to give students a working knowledge of labview in a 6 hour timeframe. The contents are: Instructor Notes.doc – this document. labviewIntroduction-SixHour.ppt – a PowerPoint presentation containing screenshots and notes on the topics covered by the course. Convert C to F (Ex1).vi – Exercise 1 solution VI. Convert C to F (Ex2).vi – Exercise 2 solution subVI. Thermometer-DAQ (Ex2).vi – Exercise 2 solution VI. Temperature Monitor (Ex3).vi – Exercise 3 solution VI. Thermometer (Ex4).vi – Exercise 4 solution subVI. Convert C to F (Ex4).vi – Exercise 4 solution subVI. Temperature Logger (Ex4).vi – Exercise 4 solution VI. Multiplot Graph (Ex5).vi – Exercise 5 solution VI. Square Root (Ex6).vi – Exercise 6 solution VI. State Machine 1 (Ex7).vi – Exercise 7 solution VI. The slides can be presented in two three hour labs, or six one hour lectures. Depending on the time and resources available in class, you can choose whether to assign the exercises as homework or to be done in class. If you decide to assign the exercises in class, it is best to assign them in order with the presentation. This way the students can create VI’s while the relevant information is still fresh. The notes associated with the exercise slide should be sufficient to guide the students to a solution. The solution files included are one possible solution, but by no means the only solution.

This project is created using the Keil ARM CA Compiler. The Logic Analyzer built into the simulator may be used to monitor and display any variable or peripheral I/O register. It is already configured to show the PWM output signal on PORT3.0 and PORT3.1 This ARM Example may be debugged using only the uVision Simulator and your PC--no additional hardware or evaluation boards are required. The Simulator provides cycle-accurate simulation of all on-chip peripherals of the ADuC7000 device series. You may create various input signals like digital pulses, sine waves, sawtooth waves, and Square waves using signal functions which you write in C. Signal functions run in the background in the simulator within timing constraints you configure. In this example, several signal functions are defined in the included Startup_SIM.INI file.
