ARC filters with modern active elements
Sedláček, Petr ; Murina, Milan (referee) ; Sedláček, Jiří (advisor)
The aim of this project is to compare the characteristics of low pass and high pass filters designed by various methods of synthesis. Firstly, the attributes and characteristics of filters and realisations of higher order filters using normed low pass filter and approximation of gain-magnitude frequency response are described and then used in application. The circuits that substitute coils directly or undirectly using the Bruton transform are discussed next. The practical part of project concerns of design of high pass and low pass itself, using two methods of synthesis. Proper real operational amplifier has to be choose for used frequency. In the final part of work the designed circuits were realized and their characteristics were measured and examined.
