Hello,

 

I designed Rx FIR filter using ADI Filter Design Wizard and got 128 filter coefficients. I have couple of questions on how to configure the Rx FIR filter.

 

1. Can Tx FIR filter be disabled when Rx FIR filter is enabled?

2. Can the interpolation factor of Tx FIR filter be different from the decimation factor of Rx FIR filter?

3. How to configure the Rx FIR filter?

 

We used the following commands to enable and configure the Rx FIR filter:

 

ad9361_set_rx_fir_en_dis(ad9361_phy, 0);

ad9361_set_rx_fir_config(ad9361_phy, rx_fir_config);

 

Regards,

Lakshmi
