Hi, as the Matlab script created by Firas needs the Filter toolbox, I have created an equivalent script for Octave.
Two differences: It uses only 'freqz' for the computation of the transfer functions For the baseband, also the images due to aliasing is plotted I think, the second point gives some valuable information. Part of the first sidelobe of the CIC filter falls into the passband of the HBF, so it is quite strong (only ~50dB attenuation). The new plot strengthens this. Plots and script is available here: http://www.kawo1.rwth-aachen.de/~lurchi/gnuradio/ Regards, Stefan -- Stefan Brüns / Bergstraße 21 / 52062 Aachen phone: +49 241 53809034 mobile: +49 151 50412019 _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
