Abstract: In a method of spectrum analysis, a sample signal, which is obtained by sampling an original signal at an original sampling rate within a sampling period, is transformed into a spectrum to be measured according to a frequency range scale. An optimum graduation interval of the frequency range scale is determined in accordance with frequency and amplitude parameters of the spectrum. An updated sampling rate is determined by multiplying the original sampling rate by the optimum graduation interval. The original signal is re-sampled at the updated sampling rate within the sampling period so as to obtain an updated sample signal. An optimum sample signal is obtained by multiplying the updated sample signal by a scale shift function that is based on the optimum graduation interval and the frequency and amplitude of the spectrum. Finally, the optimum sample signal is transformed into an optimized spectrum.
