Wide Bandpass Filter Composed of First-order and Second-Order Active High Pass Filters Simulated Using MATLAB and Multisim Live

This research aims to simulate a wide bandpass filter that is composed of first-order and second-order high pass filters that are cascaded in series. The filters are composed of 3-terminal op-amps, 1V AC source with 1 kHz frequency, luF capacitors, and 1k-ohm resistors. To determine the phase shift and frequency response, the filters are simulated in Multisim Live using AC sweep analysis. On the other hand, to acquire the step response and root locus plot of the circuits, they are treated as control systems, and their transfer function formulas were simulated using MATLAB. At the end of the study, the researchers confirmed the different properties and parameters these filters have.
