Having a control of order to the low pass filter and one for the highpass filter, since the former can be used a low-order and second normally used a higher order.

Currently the LPF is programmed in a different way and it doesn't really have an order. So the control only works for the HPF. Do you want a steeper or less steep LPF? And if so, could you please tell me why? |

ok, I thought the adjustment was for both. Now I have more clear. To my taste the LPF, should have a little more pronuciada pediente, but the current is not bad. Thanks Hans!

pronunciada pendiente = steep LPF is already VERY steep! HPF: Depend on what is used, non-phase linear or phase linear HPF. Non phase linear is already very steep and also have order settings, so i guess you mean on phase linear HPF. With aditional checkbox filters is steeper but there is also another difference. Phase linear HPF filter is placed after MB and non phase linear HPF is placed before AGC. LPF is in both cases placed after MB. |

Correct!, sorry.  Quote: LPF is already VERY steep!
That order or db / octave has?Quote: HPF: Depend on what is used, non-phase linear or phase linear HPF. Non phase linear is already very steep and also have order settings, so i guess you mean on phase linear HPF.
My confusion comes because I thought the order was applied to the filter LPF and HPF, now clear to me no and it depends on what the filter applied in one place or another.With aditional checkbox filters is steeper but there is also another difference. Phase linear HPF filter is placed after MB and non phase linear HPF is placed before AGC. LPF is in both cases placed after MB. I think it would be good to choose the slope of any of the HPF and that instead of being a graduate of "order" is in dB / octave. If I remember correctly, is 6 db / octave for each order, can it be? Bojcha Thanks for the clarification.
