Non-standard sample rate reset to 11025 Hz
Signal analysis at 0,50 into the file...
Apparent carrier freq: 2399,87 Hz, suggested sampling freq: 11024 Hz
Meteor/Resurs analysis: mean signal: 2415,86
256 Hz tone: averge: 0,026 (req: 0,095), peak: 0,002 (req: 0,080)
Analysis - checking auto-correlation
ACF for F = 0Hz: acf[0] = 1,02, [t/2]=-0,79, [t]=0,98, [3t/2]=-0,81, ratio [t] / avg([t/2], [3t/2])=-1,21
ACF: minimum 7,8%, mean 49,6% of peak signal
ACF does not suggest double-speed signal
NOAA analysis: mean signal: 2469,41
832 Hz tone: average: 0,028 (req: 0,015), peak: 0,100 (req: 0,055)
