Hi,

Please find one example attached where filter cut-off is changed dynamically. By default, Filter is configured to LPF, 50KHz cut-off. If you press the switch , the filter will change to LPF, 10KHz cut-off. If you press the switch again, it will toggle the Filter back to LPF, 50KHz cut-off.

Best Regards,
Vasanth
