• Depending on signal level: Detection principle • 40 dBHz: can be easily heard in speaker • 20 dBHz: can be heard with headphones •
Performance Simulation • G3RUH generated sample WAV files with 3 dBHz (735 seconds) to test analysis techniques • G3RUH used own analysis package, same algorithm implemented in SCILAB (DH2VA) • Record audio samples • Perform FFT • Add to previous FFT results (integrate) • Use 10 Hz convolution filter to <strong>com</strong>pensate for finite VFO step size • Same algorithm on two different machines and s<strong>of</strong>tware packages perform equally well and within expectations Amsat-UK Colloquium 2006 Achim Vollhardt, DH2VA/HB9DUN 19
