This board does not substitute the medical device under study. The results of the experiments have no medical value. In this course we will study the devices that allow the passage of biomedical signals with given characteristics, while attenuating those that do not comply with the required parameters. They are just for demonstration purposes

The board is divided in five sections, and in each one there are more than one filter of the same kind. The board allows the study and the functional check on active filters carried out with operational amplifiers. The board is supplied complete with a set of stackable, plug in cables of suitable lengths and colours and with a training manual.
Power supply: ± 15 Vdc, 750 mA
It is possible to study, respectively:
High pass filter VCVS of the first and second order
Low pass filter VCVS of the first and second order
Universal filter of variable state type
Multiple feedback band pass filter
Dual T band stop filters.
