摘要：
In order to calculate the minimal phase spectrum from the (logarithmic) amplitude spectrum it is customary to use the Hilbert transformation. For a series consisting of N values, the number of necessary computing operations is proportional to N**2. It is shown that the so called Kolmogorov factorization makes it possible to reduce the number of steps. If, in addition, the Fourier transformation is used, it is possible to obtain the same result with a number of computing operations which is proportional to N log N.
