Hi, It appears that gr.message_sink and gr.msg_queues are for digital data. but my flowgraph (periodogram) is for analog samples,
complex baseband samples from usrp --> stream to vector (vectors of fft_size) --> FFT --> complex to mag squared --> (sink or block to be determined) Is their no choice other than file sink?

Or, you need to create your own block in c++ or python. If c++, the "how to write a block example" is a good reference. If python, the wxgui sinks are a good reference (see gr.message_sink and gr.msg_queues to get data out of the stream and into python). -Josh -----Inline Attachment Follows----- _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
