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.

使用 SQL 合计函数 你可以确定数据组的各种统计。你可以把这些函数用于查询和合计表达式，条件是在具备 SQL特性的 QueryDef对象中或在创建基于SQL查询的 Recordset对象时-You use the SQL aggregate functions to determine various statistical data sets. You can put these functions together for query and expression, on the condition that the availability of SQL characteristics QueryDef object or create a SQL query based on the Recordset object
