Member Function Documentation

m_lowpass_integer_add_sample()

void m_lowpass_integer_add_sample	(	struct m_lowpass_integer *	mli,
		int64_t	sample
	)

Filter a sample.

Parameters

mli	self-pointer
sample	The value to filter

References xrt::auxiliary::math::IntegerLowPassIIRFilter< Scalar >::addSample().

m_lowpass_integer_create()

struct m_lowpass_integer * m_lowpass_integer_create	(	int64_t	alpha_numerator,
		int64_t	alpha_denominator
	)

Constructor.

Note

Taking alpha, not a cutoff frequency, here, because it's easier with the rational math.

Together, the two parameters specify the alpha value used to blend between new input and existing state. Larger values mean more influence from new input.

Parameters

alpha_numerator	The numerator of the alpha value. Must be greater than 0 and less than alpha_denominator
alpha_denominator	The denominator of the alpha value. Must be greater than 0.

Returns

null if a parameter is out of range

m_lowpass_integer_destroy()

void m_lowpass_integer_destroy

(

struct m_lowpass_integer **

ptr_to_mli

)

Destroy a lowpass integer filter.

Does null checks.

Parameters

ptr_to_mli

Address of your lowpass integer filter. Will be set to zero.

m_lowpass_integer_get_state()

int64_t m_lowpass_integer_get_state

(

const struct m_lowpass_integer *

mli

)

Get the filtered value.

Probably 0 or other meaningless value if it's not initialized: see m_lowpass_integer_is_initialized

Parameters

mli	self-pointer

References xrt::auxiliary::math::IntegerLowPassIIRFilter< Scalar >::getState().

m_lowpass_integer_is_initialized()

bool m_lowpass_integer_is_initialized

(

const struct m_lowpass_integer *

mli

)

Get whether we have initialized state.

Parameters

mli	self-pointer
