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();
