WebH.S. Chen Chapter1: Classification of signals and systems 10 • The above three properties are not true for a discrete-time signal x[n]=ejΩ0n. 1. For a discrete-time signal, we have x[n]=ej(Ω0+2π)n = ejΩ0n ×ej2πn = ejωon i.e., the signal x[n]atfrequency(Ω0 +2π) is the same as that at frequency Ω0, that is unlike the continuous case: ejw1t = ejw2t if w 1 = w2 WebMay 22, 2024 · The second-most important discrete-time signal is the unit sample, which is defined as. δ [ n] = { 1 if n = 0 0 otherwise.
