Detailed Description

output is the moving sum of the last N samples, scaled by the scale factor

Member Typedef Documentation

virtual int gr::blocks::moving_average_ff::length ( ) const [pure virtual]

Get the length used in the avaraging calculation.

static sptr gr::blocks::moving_average_ff::make	(	int	length,
		float	scale,
		int	max_iter = `4096`
	)		`[static]`

Create a moving average block.

Parameters:

length	Number of samples to use in the average.
scale	scale factor for the result.
max_iter	limits how long we go without flushing the accumulator This is necessary to avoid numerical instability for float and complex.

virtual float gr::blocks::moving_average_ff::scale ( ) const [pure virtual]

Get the scale factor being used.

virtual void gr::blocks::moving_average_ff::set_length ( int length ) [pure virtual]

Set the length.
