I've attached an example that uses a narrow-band, real-only signal source, with everything running at an arbitrary sample rate of 150Ksps. It uses a Hilbert transform, followed by a decimate-by-two bandpass filter. Without the bandpass filter, there will still be a residual "image" frequency in the complex output of the Hilbert transform, and since we're decimating by two anyway, I thought I'd put in a bandpass filter. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org |
