Active Filters.Active Filters
Experimental training board has been designed specifically to study characteristics of various types of active filters. This Training Board includes low pass, high pass, band pass and notch filters. The filter circuits are designed using second order Butter worth polynomials and provide unity gain in the pass band. Practical experience on this board carries great educative value for science and engineering Students.
