Abstract: This application note presents an overview of electronic margining and its value in detectingpotential system failures before a product ships from the factory. It is a calibration method that effectivelypredicts and allows adjustments to improve product quality. Margining also can be used to sort productsinto performance levels, allowing premium products to be sold at premium prices. We discuss thedownside of sorting and suggest alternative ways to segregate products.

基于通用集成運算放大器,利用MASON公式設(shè)計了一個多功能二階通用濾波器,能同時或分別實現(xiàn)低通、高通和帶通濾波,也能設(shè)計成一個正交振蕩器。電路的極點頻率和品質(zhì)因數(shù)能夠獨立、精確地調(diào)節(jié)。電路使用4個集成運放、2個電容和11個電阻,所有集成運放的反相端虛地。利用計算機仿真電路的通用濾波功能、極點頻率和品質(zhì)因數(shù)的獨立控制和正交正弦振蕩,從而證明該濾波器正確有效。 Abstract: A new multifunctional second-order filter based on OPs was presented by MASON formula. Functions, such as high-pass, band-pass, low-pass filtering, can be realized respectively and simultaneously, and can become a quadrature oscillator by modifying resistance ratio. Its pole angular frequency and quality factor can be tuned accurately and independently. The circuit presented contains four OPs, two capacitors, and eleven resistances, and inverting input of all OPs is virtual ground. Its general filtering, the independent control of pole frequency and quality factor and quadrature sinusoidal oscillation were simulated by computer, and the result shows that the presented circuit is valid and effective.

pdnMesh is an automatic mesh generator and solver for Finite Element problems. It will also do post-processing to generate contour plots and Postscript printouts. GUI support using GTK or MFC (Win32) is available. The problem definition can be done in any form and given to pdnMesh as an input data file. Drawing Exchange Format (DXF) files can be directly imported to pdnmesh. The quality and the coarseness of the mesh can be controlled by giving input parameters.

ATmega8 taillight circuitA more complex C program that implements different flashing patterns under the control of both the push buttons and potentiometer. Use your imagination to come up with some novel ideas here. Remember however that more marks are to be awarded for the quality of the code than for the novelness of the patterns.
