| Abstract: | In this paper, Power spectrum of CAP (carotid pulse) by periodogram and AR model is given, respectively. Comparison of these two methods show that periodogram method is superior to the AR model, in point of the stability of peak and distributing of the power spectrum. |

| Keywords: | CAP power spectrum periodogram autoregressive model |
