Member Function Documentation

std::pair<double, double> sr_math_utils::filters::LowPassFilter::compute	(	double	q,
		double	timestamp
	)		[inline]

Computes the filtered value and its derivative.

Parameters:

q	the newly received value.
timestamp	the time at which the last measurement was made (in sec).

Returns:

a pair containing the filtered value first, then the derivative.
