nrf_dsp_crest_f32()

flt32_t nrf_dsp_crest_f32	(	const flt32_t *	p_input,
		uint16_t	num,
		const flt32_t *	p_absmax,
		nrf_dsp_stat_ctx_f32_t *	p_ctx )

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

Calculates Crest Factor (Peak to RMS) in a floating-point vector.

Parameters

[in]	p_input	Pointer to the input vector
[in]	num	Number of samples in input vector
[in]	p_absmax	Optional pointer to the absolute maximum(peak) in the vector
[in,out]	p_ctx	Optional pointer to the statistics context, this function will use p_ctx->value.tss for calculation if it exist

Returns

flt32_t Crest Factor (Peak to RMS) in the vector
