It is shown how to obtain optimum FIR bandpass filters by frequency transformations from known lowpass or bandpass designs. Firstly, from lowpass filters one obtains a special class of bandpass filters: the symmetrical bandpass filters satisfying amplitude characteristic in arithmetic symmetry with respect to the point Ω=π/2. Secondly, the scaling of the bandpass extraripple filters yields new bandpass filters which are still optimum over new frequency ranges; thus an infinite number of solutions can be obtained from a finite number of extra-ripple filters.

This study propose the development of testing equipment for a fusing technology that is able to have the characteristics of conductors after demolishingthe dielectric between two pole layers of anti-fuse. Using the developed equipment, we have analyzed the results between properties of each anti-fuse switching element made by famous FPGA companies, Actel and QuickLogic and ETRI This equipment is composed with CPU 8031 to control all of elements, oscillator with the frequency of 12 MHz to supply the clock of machine cycle to CPU, reset circuit to initialize CPU and guarantee the stabilization of CPU with a voltage detection from the source of electric power, latch to separate lower addresses, ROM to store a execution program, and decoder to assign a memory map. The behavior of hole equipment are performed by programs stored in ROM. The advanced study is to develop a hardware programmer, which is an equipment of programming anti-fuse switches to impalement a circuit designed with a CAD system.
