is it doable for FMCOMMS1-EBZ to do 25KHZ pi/4 DQPSK
There isn't anyone here with the name "Support"
The board does have places for a filter - look at sheet 3 of the schematic - you will need to design your own filter, and replace those components. (L41, L42, L24, L29, C264, C114) - don't change R51, R52, R54, R57 as those are for common mode settings. Same for the "I" channel above that.
In the latest MATLAB release (2013b), there is the "FPGA Radio Support
Package" that supports FMCOMMS1-EBZ, and comes with the QPSK example. That
is something you can look into. You can get the support package from the

Thank u for the reply
what about the narrow band 25KHZ
Are you asking whether you can put out a 25KHz signal?
Did you try this on your board?
I have the board
but the question is does your filter tune to 25KHZ
does this board support narrow band for 25 khz and 12.5 khz
what interesting is that we cant find it anywhere and the support team dont know
We are the support team - we know.
Filtering in the analog domain?
Filtering in the RF side? Baseband side?
Filtering in the digital domain?
Need more information.
From FPGA standpoint we have subcontractor for it but they were unable to determin if you board support
narrow band for APCO and TETRA use
so does this RF board has a Baseband configurable low-pass filter to 25 KHZ and 12.5 KHZ
