Abstract :
A new technique for power spectrum analysis is introduced theoretically evaluated and experimentally verified with a prototype. This technique is based on the estimate of the autocorrelation function with different delays. The proposed sampling strategy is random in the time domain and equally spaced, synchronous with the signal, in the delay domain. It is shown that the estimate of the power spectral components is asymptotically unbiased and the experimental results are also given
