Method Detail

getNextValidNumberofSamples

public int getNextValidNumberofSamples(int proposedNumberofSamples)

FFT size (must be 2^n), i.e. the number of samples to be transformed. Valid number of samples is calculated.

Overrides:

getNextValidNumberofSamples in class Dft

Returns:

Number of samples that are transformed must be 2^n. Number of samples >= proposedNumberofSamples
