基于可编程跨导运算放大器POTA低通有源滤波器设计。该文给出了基于可编程跨导运算放大器(POTA)的有源滤波器设计方法，能在一定范围内实现跨导值程控调节, 提高调节精度和准确度。并且利用Jacobi 法求解相似对角形矩阵，避免解高次方程的难题。所设计的有源滤波电路不易受分布电容的影响，稳定性好、灵敏度低。本文给出了设计实例，显示了该方法的优点。-Based on programmable transconductance operational amplifier POTA low-pass active filter design. In this paper, based on the programmable transconductance amplifier (POTA) of the active filter design method that can realize in a certain range transconductance value of program-controlled adjustment, improve precision and accuracy regulation. Jacobi method and use a similar matrix of angular, high-equation solution to avoid problems. Designed active filter circuit less susceptible to the effects of distributed capacitance, good stability, low sensitivity. In this paper, design examples, showing the advantages of the method.

"Calcoolation" is a puzzle game that at first looks like the popular Sudoku. Just like in Sudoku, you have an N x N matrix, where the digits 1 through N must be placed in each column and in each row without repetition. The difference lies in the fact that there are blocks of cells, named "cages", where specific operations involving the numbers in the cells must satisfy the specific result displayed in the cage.

(1) 设计一个程序，用于根据用户输入的命令行参数数量来计算长方形、正方形、三角形的面积。如果输入的参数为一个、二个、三个则它们应分别对应正方形、长方形、三角形，如果没有参数，则通过异常处理方法现实错误消息。（用于计算面积的方法是一个重载的方法。提示：定义一个抽象的父类，并提供一个抽象的方法area(). 再派生出三个子类，重写area()方法，然后在main方法中用多态来实现具体的面积函数的调用）。-(1) design a program based on user input for the command line parameters to calculate the number of rectangular, square, triangle area. If the input parameter is one, two, three then they should correspond to a square, rectangle, triangle, without parameters, exception handling through the real error message. (Used to calculate the area is an overloaded method. Note: the definition of an abstract parent class, and provides an abstract method area (). To send birth to three sub-classes override area () method, and then in main method using multi-state to achieve a specific area of a function call).
