Design of a General Purpose Sampling Integrated Module

AC sampling technique is the foundation of computer aided electrotechnics measurement. In practical applications, in order to improve the accuracy of electrotechnics measurement, especially to improve the accuracy of power measurement, it is very difficult for engineers to design both the software and hardware of AC sampling. (Usually the circuits are bulky and the software is quite complex.) This paper presents a new AC sampling integrated module design that can simplify both the software and hardware design of AC sampling. This new design use AHDL language to describe the complex AC sampling software and hardware within EPLD modules. With the cooperation of A/D conversion module, it is can be used as a specific AC sampling chip.
