virtual bool gr::analog::pwr_squelch_ff::gate

(

)

const [pure virtual]

Implements gr::analog::squelch_base_ff.

static sptr gr::analog::pwr_squelch_ff::make	(	double	db,
		double	alpha = 0.0001,
		int	ramp = 0,
		bool	gate = false
	)		[static]

Make power-based squelch block.

Parameters:

db	threshold (in dB) for power squelch
alpha	Gain of averaging filter
ramp	sets response characteristic.
gate	if true, no output if no squelch tone. if false, output 0's if no squelch tone.
