Larger DSP buffers = sharper filters with more delay. Smaller DSP buffers = "broader" filters with less delay. Lower sample rate = sharper filters with more delay. Higher sample rate = "broader" filters with less delay. The same holds true for both RX and TX but on TX you have probably already generated a good signal so the filter doesn't buy you very much. Go for smaller buffers to minimize delay/latency on TX. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.931.492.6776 (USA) (+1.931.4.WB6RQN) _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
