Overview

Calculates the log10 power value for each input point.

Dispatcher Prototype

void volk_32fc_s32f_power_spectrum_32f(float* logPowerOutput, const lv_32fc_t*
complexFFTInput, const float normalizationFactor, unsigned int num_points) 

Inputs

• complexFFTInput The complex data output from the FFT point.
• normalizationFactor: This value is divided against all the input values before the power is calculated.
• num_points: The number of fft data points.

Outputs

• logPowerOutput: The 10.0 * log10(r*r + i*i) for each data point.

Example

int N = 10000;
 
volk_32fc_s32f_power_spectrum_32f();
 
volk_free(x);
