Need help for tutorial 04-Polyphase-Channelizer

[SimoneDag99]

Hi to everyone. I'm studying the implementation of the channelizer in this tutorial and I cannot understand two things in "polyphase_fir_app.cpp". First: where "taps_M16_init.h" comes from? Second: line 14, how does it work without arguments specified?

Thanks you for your replies.

Hi @SimoneDag99

The file polyphase_fir_app.cpp is not compiled as part of the full system. polyphase_fir_graph is a subgraph and the file polyphase_fir_app.cpp is used to test it independently. But as part of the full system polyphase_fir_app.cpp is not used, thus even if taps_M16_init.h the full system is compiling
