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

Finds Peak-to-Peak amplitude for Low and High frequency components of signal, represented as a INT16 fixed-point vector.

Parameters

[in]	p_input	Pointer to the input vector
[in]	num	Number of samples in input vector
[in]	window_size	Determines window size for calculation moving average filter sum, window_size affect attenuation for frequencies
[out]	p_pk2pk_lf	Pointer to store Peak-to-Peak amplitude for Low frequency component
[out]	p_pk2pk_hf	Pointer to store Peak-to-Peak amplitude for High frequency component
