QT GUI Fast Auto-Correlator Sink

This block uses the Wiener Khinchin theorem that the FFT of a signal's power spectrum is its auto-correlation function.

FAC Size controls the FFT size and therefore the length of time (samp_rate/fac_size) the auto-correlation runs over.

Parameters
(R): Run-time adjustable


 * Sample Rate
 * default: samp_rate


 * FAC Size
 * FAC Size controls the FFT size (default: 512)


 * FAC Decimation
 * default: 10


 * Output
 * options: [dB, Normalized]


 * Title
 * display title


 * Show Grid
 * options: [Yes, No]


 * Auto-Scale
 * options: [Yes, No]


 * Y Min
 * default: 0


 * Y Max
 * default: 1
