WebOct 15, 2024 · 3 Answers Sorted by: 6 If you are talking about a given signal as "a deterministic realization of a phenomenon", it can be periodic, but not really random. However, some physical systems are prone to produce randomness and periodicity, like rotating machines, gears, cyclic engines, that produce signals similar to: WebNov 2, 2015 · \$\begingroup\$ It would probably be more clear if you pointed out in you question that the context is discrete-time signals. I (and from the comments, others) didn't pick up on this just from the form of the signal. For a discrete time signal to be periodic, the period of the (notionally) underlying continuous-time signal should have mutual harmonic …

WebThe periodic signal is defined as the signal that repeats itself periodically in the time domain. So firstly define the behavior of the signal on the time domain for a certain period … Web2. Determine whether the discrete time signals below are periodic. If the signal is periodic, determine its fundamental period. (a) x [n] = − 3 ⋅ sin (0.01 ⋅ πn) (b) x [n] = 1 + cos (2 πn ) (c) x [n] = cos 2 (3 1 n) attack on titan o
Periodic Signal - an overview ScienceDirect Topics
WebDiscrete periodic signals. Consider signals of the form x: DiscreteTime → Reals, where the set DiscreteTime = Integers provides indices for samples of the signal. Such signals are called discrete-time signals.A discrete-time signal is periodic if there is a non-zero integer p ∈ DiscreteTime such that for all n ∈ DiscreteTime,. x(n + p) = x(n).. Note that, somewhat … WebMay 22, 2024 · Periodic and Aperiodic Signals. When a function repeats itself exactly after some given period, or cycle, we say it's periodic. A periodic function can be mathematically defined as: (8.1.1) f ( t) = f ( t + m T) m ∈ Z. where T > 0 represents the fundamental period of the signal, which is the smallest positive value of T for the signal to repeat.
