This paper presents a testing of three insulators namely solid fluid and gas for choosing the best electric insulators. In order to generate the ozone gas the insulator must be selected in electrode set. Nowadays the insulators do not have the optimal test procedure for getting total efficiency. Therefore in this paper a design of ozone generator is proposed by using the fundamental of electric field stress. The ozone generator is a coaxial cylindrical electric type that has solid insulator in center of glass tube. This solid insulator will be dielectric among the high voltage electrodes. Ozone gas will generate in this air gap. This paper also focuses on the insulator testing of three insulators. It will find the efficiency of 3 insulators and compares them with the density and stress of ozone gas. The experimental results show the performance and ensure the optimal ozone generator design.

This article describes an efficient approach to the implementation of bit-serial lattice wave digital filters based on field programmable gate array (FPGA). In this paper a time schedule of all of the bit-serial two-port adaptors is presented as a bridge between conception and completion. Finally with the satisfying frequency response the filter is successfully tested by both computer simulation and real signal measured from the programmed FPGA.
