We are going to test the filter, giving as an input a sum of different cosines using different AC voltage sources in series and an Oscilloscope. We are confident that the filter works properly. Below we can see the final schematic.Ĭonnecting a Bode-Plotter, we take exactly the same above Transfer function graph in Multisim. It satisfies all the above requirements.Īfter using the Matlab script to calculate all the required components, we proceed with the design of the circuit. In the below graph we can see the Transfer function of the filter. We would like to implement a High-Pass Butterworth filter with the below requirements of frequencies and attenuation levels: Note that the pdf files provide much more detail, in case needed.

The scripts, multisim files as well as the pdf files with detailed description of the whole steps that were folllowed can be found in the respective folders for each filters.īelow, we are going to present briefly the requirements, the final Transfer Function with all Units that were used, the schematic, a Transient Analysis as well as a Fourier Analysis in Multisim of the input and output signal, in order to prove the efficiency of the designed filter. After that, the schematic was designed in MULTISIM and the application was compared with the analytical solution in order to assure that the respective filter works properly. Also, MATLAB was used for the calculation of the parameters of the electronic components. Originally, the analytical solutions for each filter was implemented in MATLAB. This repository contains the implementation of four different filters:
