In addition to the Butterworth filter, now you can build the IIR filters with the Chebyshev type I (band-pass ripple) filter or Chebyshev type II (stop-band ripple) filter. | In addition to the Butterworth filter, now you can build the IIR filters with the Chebyshev type I (band-pass ripple) filter or Chebyshev type II (stop-band ripple) filter. | ||

For the band pass and band stop filters, the filter order is 2*N, and N can be selected from 1 to 30 in the Office mode, and between 1 to 10 in the Connected mode now. In the previous NVGate version, the maximum value of N was 5. | For the band pass and band stop filters, the filter order is 2*N, and N can be selected from 1 to 30 in the Office mode, and between 1 to 10 in the Connected mode now.

To guarantee the stability of the filter, there are certain constraints on the value of the cut-off frequency. Compared with previous version of NVGate, such constraints are relaxed significantly now. | To guarantee the stability of the filter, there are certain constraints on the value of the cut-off frequency.
