2022-04-17 Thread George Edwards
Dear Gnuradio Community, I am writing an OOT signal processing algorithm in C++ that requires both fft and ifft. I use the Gnuradio C++ library to get the fft and ifft functions. To confirm understanding of setting up these functions, I wrote C++ OOT blocks for both fft and ifft blocks. I ran a co
