Hi, i have been trying to build a block for (for transmitter and receiver )bandpass filter for 20 Khz bandwith in vivado for pluto sdr i know it might be wrong because there is a limit for 528kbps so i am wondering if i would build fir filter up to 2 Mhz carrier frequency , would it work ? or do i need to do interpolation/decimation filters set up, ( this is my first step to build a multiband filter design and each filter will have gap of 500 KHz between each other), thank you in advance
