Hi, I want to frequency shift my signal down to zero Hz. I can do that with the ddc and a freq_xlating_fir_filter block, but there is always some frequency error. Is there a block that will auto fine tune the shift frequency so the output is as close as possible to 0 Hz?
If so, is there an example of how to use it? Another potential complication is that there is no constant carrier for the signal I'm receiving. Thanks, Hans -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
