nrf_dsp_zcr_i32()

int16_t nrf_dsp_zcr_i32	(	const int32_t *	p_input,
		uint16_t	num )

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

Counts Zero-crossing rate of a INT32 fixed-point vector.

Parameters

[in]	p_input	Pointer to the input vector
[in]	num	Number of samples in input vector

Returns

int16_t Zero-crossing rate in the vector, multiplied by NRF_DSP_PERCENTAGE_TO_INT_FACTOR
