The fir_filter_XXX does time-domain convolution. You'd pass it a decimation of 1 and the taps would be the signal you want to convolve against. The fft_filter_XXX does fast convolution in the frequency domain. http://gnuradio.org/doc/doxygen/page_filter.html Tom _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
