No, the sum of a periodic and an aperiodic signal can be periodic. Does paying down debt in an S Corp decrease profitability? Period of two periodic functions with same period, Decomposition of periodic spikes into frequencies. 1. 1 The _______ wave is the simplest analog signal. Asking for help, clarification, or responding to other answers. }, You may be interested in: It only takes a minute to sign up. Analog Communication is a data transmitting technique used to transmit data including video, audio, electrons, image etc. I have three question on periodic and aperiodic signal that I have doubt about also I couldn't find the answer on searching so I am asking here. $$\left|f(x)\right|=\left|f(x+kT)\right|<\varepsilon_k$$ with A one-sided spectrum with equidistant Dirac impulses also implies a periodic time-domain signal, but that signal is necessarily complex-valued because its spectrum has no Hermitian symmetry, as required for real-valued signals. So they can conclude that $f(x)$ is aperiodic. If a signal isn’t periodic, it’s aperiodic. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Please Login Consequently, $f(x)$ would be a constant function, which is clearly not the case. So it is periodic, isn't it?
