If we know the signal is N-periodic then all the information of the signal is captured by the above interval.WebThe DTFS coefficients of x3_all[n] in one period can be translated to the DTFS coefficients of x3[n] in one period. Therefore x3[n] = x3_all[n]. We’ve already had the conclusion that x3[n] is purely real, thus x3_all is also real.device manager windows shortcut
