Analysis of Passive and Active Filters Using Modified Nodal Approach

This study presents analysis of passive and active filters using modified nodal approach (MNA). The transfer functions of the filter circuits are added into the study. The results of simulations have been demonstrated on practical examples and the frequency-gain/frequency-output characteristics have been given for these examples. Besides, graphic user interfaces (GUI) have been prepared to implement analysis of the circuits and to get fundamental concepts of the filters more comprehensible.
