How can power spectral density of non periodic signal be calculated?(a

1.	How can power spectral density of non periodic signal be calculated?(a) By integrating(b) By truncating(c) By converting to periodic(d) None of the mentionedThis question was addressed to me during an interview for a job.I would like to ask this question from Spectral Density and Autocorrelation in chapter Signals and Spectra of Digital Communications
Answer» The CORRECT choice is (b) By truncating For explanation I would say: A power signal usually is a periodic signal. But power spectral density of NON periodic signal can be CALCULATED by truncating it and OBSERVING it in the range of (-T/2,T/2).
