Detailed Description

Random number source.

Generate random values from different distributions. Currently, only Gaussian and uniform are enabled.

Member Typedef Documentation

virtual float gr::analog::fastnoise_source_s::amplitude ( ) const [pure virtual]

static sptr gr::analog::fastnoise_source_s::make	(	noise_type_t	type,
		float	ampl,
		long	seed = `0`,
		long	samples = `1024 *16`
	)		`[static]`

Make a fast noise source.

Parameters:

type	the random distribution to use (see gnuradio/analog/noise_type.h)
ampl	a scaling factor for the output
seed	seed for random generators. Note that for uniform and
samples	Number of samples to pre-generate Gaussian distributions, this should be a negative number.
