Questions about the output sampling rate of the DUC(interpolation filter) of the USRP N210

1. What is the maximum sample rate for Usrp?
2. What is the master clock rate of N210?
3. What is the effect of interpolation on filter design?
4. What is sampling rate of a filter?

What is the maximum sample rate for Usrp?

The maximum supported sample rate is 200 Msps if using one channel and 100 Msps if using both channels. TwinRX only supports instantaneous bandwidth up to 80 MHz, so a sample rate of 100 Msps or less is sufficient for all applications.

What is the master clock rate of N210?

One is the N210's main clock rate is 100MHz, the setting Sampling rate is 5MHz.

What is the effect of interpolation on filter design?

The interpolation filter then uses the lowpass FIR filter H(z) to remove the images. Therefore, this lowpass FIR filter is an anti-imaging filter. The interpolation filter then returns an output signal y(n) with the new sampling frequency.

What is sampling rate of a filter?

The Audio Engineering Society recommends 48 kHz sampling rate for most applications but gives recognition to 44.1 kHz for Compact Disc (CD) and other consumer uses, 32 kHz for transmission-related applications, and 96 kHz for higher bandwidth or relaxed anti-aliasing filtering.
