The method involves reading out the time signal section-wise by a window function and an overlapping window. The Fourier transformation of the readout signal is executed in a frequency chamber, particularly by executing a discrete Fourier transformation. An energy value for each bin is calculated from the frequency amplitude, which results from Fourier transformation, particularly by squaring the real and imaginary parts or creating a derived energy value. An independent claim is included for a computer program with a program code for executing the method. |
