Hi all, I'm working on the gen2_reader project and got some trouble with the amp block. We use the gr_multiply_const_ff to amplify the power of signal.
amp = gr.multiply_const_ff(amplitude) tx = uhd.usrp_sink(options.args, uhd.io_type.COMPLEX_FLOAT32, num_channels=1,) self.connect(self.reader, amp, to_complex) self.connect(to_complex, tx) I found an threshold of amplitude, when amplitude < 40, the signal tx block transmited looks like the amp20,png (that what we want) and when amplitude >= 40, the signal is just the same to amp5000.png which get several peaks in the signal we want to eliminate. As the amplitude reflect the power of signal we transmit and need to be set at least 5000 to power the tag, so we have to eliminate the peaks. Is there some methods to deal with the amplitude, or just replace the multiply_const_ff block with any other blocks? Thanks for any advice Lee <http://gnuradio.4.n7.nabble.com/file/n45018/amp20.png> <http://gnuradio.4.n7.nabble.com/file/n45018/amp5000.png> -- View this message in context: http://gnuradio.4.n7.nabble.com/trouble-with-gr-multiply-const-ff-tp45018.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
