Hi, Thanks for reply. I want to measure phase between reference signal and signal coming from DUT(Device Under Test). It may possible that due to non-linear characteristic of the device, there are changes in frequency and amplitude of signal. In this case the method you mentioned will give correct

Tom, Thank you for the help. But, even that didn't work. I tried a different approach. I configured the "Constellation Object" block with the* symbol map *and the *constellation points*. Then, I called it in the argument of the "Constellation Decoder" block. And it worked. I am still wondering

Re: [Discuss-gnuradio] Problem with undefined symbol in new block created by gr_modtool in 3.7.2

The first place I'd look is in your_block.h. Did you remember to declare any public member functions to be pure virtual in that file, and then declare your (non-virtual) functions in your_block_impl.h? If you forgot to declare pure virtual functions, i.e., "virtual return_type your_block(args_li

Ah, nevermind about the wiki edit. The use of pure virtual functions is already discussed in http://gnuradio.org/redmine/projects/gnuradio/wiki/BlocksCodingGuide . Still, the gr_modtool addition may be useful. -Original Message- From: discuss-gnuradio-bounces+sean.nowlan=gtri.gatech...
