SPECIFICATION

Panels made in metal case with bench support and the electrical scheme on the front panel. The board must allow the study and the functional check on active filters carried out with operational amplifiers. The board shall be divided in five sections, and in each one there will be more than one filter of the same kind. It must be possible to study, respectively: low-pass filter VCVS of the first and second order, high-pass filter VCVS of the first and second order, multiple feedback band-pass filter, universal filter of variable-state type, dual T band-stop filters, This panel shall have the aim  to recall and to verify the bases about the active filters using operational amplifiers, analyzing the approximation techniques of Butterworth, Bessel and Chebyschev and some typical circuital configurations. Power supply: ± 15 V, 750 mA. Experiments: Butterworth filter of the 2° order, Bessel filter of the 2° order, Chebyschev filter of the 2° order, Filter of the 1° order, Butterworth band filter of the 2° order, Narrow band filter, Low-pass filter, High-pass filterBand-pass filter,  State variable notch filter, Twin-T notch filter without feedback, Twin-T notch filter with feedback.
