nrf_dsp_pk2pk_lf_i8_s()

int16_t nrf_dsp_pk2pk_lf_i8_s	(	const int8_t *	p_input,
		uint16_t	num,
		size32_t	stride,
		size32_t	window_size )

#include <include/nrf_edgeai/dsp/statistic/nrf_dsp_pk2pk.h>

Finds Peak-to-Peak amplitude for Low frequency component of signal, represented as a INT8 fixed-point vector, using values ​​in increments of 'stride'.

Parameters

[in]	p_input	Pointer to the input vector
[in]	num	Number of samples with 'stride' in input vector
[in]	stride	Vector element offset stride
[in]	window_size	Determines window size for calculation moving average filter sum, window_size affect attenuation for frequencies

Returns

int16_t Peak-to-Peak amplitude for Low frequency component
