- Abstract:
- Multi-tone signals are discrete-spectrum signals with spectral components located at non-harmonically related frequencies. Their spectral analysis can be performed in short observation intervals by means of a method that combines the use of a virtual time domain and statistical techniques. The contributions to uncertainty that specifically arise from the implementation of the method are discussed in the paper and a study is developed to optimize the measurement technique in the case of bi-tone, periodic or not, signals. Finally, experimental results, which confirm theory, are reported and discussed.
