VRfAmpldB

Routine

void VRfAmpldB (const float ampl[], float dB[], int N)

Purpose

Convert each value in an array of amplitudes to a decibel value

Description

  dB[i] = 20 * log10(ampl[i]),  0 <= i < N.

Parameters

-> const float ampl[]

Input amplitude array (N elements). This values must be non-negative.

<- float y[]

Output array of decibel values (N elements). The output array can be the same as the input array.

-> int N

Number of elements in the arrays (may be zero)
