(a) Only x 1(t) can be sampled without aliasing. (b) Only x 1(t) and x 2(t) can be sampled without aliasing. (c) Only x 1(t) , x 2(t) and x 3(t) can be sampled without aliasing. (d) All the signals can be sampled without aliasing. Your Answer: WebbROC consists of strips parallel to the j 00 -axis in the s-plane. ROC does not contain any poles. If x (t) is a finite duration signal, x (t) = 0, t 1 < t < t 2 and is absolutely integrable, the ROC is the entire s plane. If x (t) is a right sided signal, x (t) = 0, t > t o, the ROC is of the form R {s} > max {R {P K }} black phone mason

For the above to happen, X (z) must have a region of convergence that includes the unit circle z = 1 e j ω.There are discrete-time signals for which we cannot find their DTFTs from the Z-transform because they are not absolutely summable, i.e., their ROCs do not include the unit circle. black phone memesWebb˛ iscalled theRegion of Convergence(ROC) • To avoid confusion, we sometimes write ROCxto indicate the ROC of the Laplacetransformofasignalx(t) • Note that the ROC of a causal signal (of exponential order) is aright-half plane(unlessσc=−∞,ofcourse) • ItcanalsobeshownthatX(s)isanalyticon its ROC The Laplace Transform 9 black phone missing poster

"WebbConsider the signal x(t) = e2tu(t). For positive values of t this signal grows exponentially without bound, and the Fourier integral does not converge. However, we observe that the modiﬁed signal φ(t) = x(t)e−σt does have a Fourier transform if we choose σ > 2. Thus φ(t) can be expressed in " - The roc of the signal x t u t is

Webb9 juli 2024 · The z-transform is primarily used to convert the discrete time domain signal into discrete frequency domain signal. The z-transform for LTI system is defined as. Due to its convolution property, the z-transform is a powerful tool to analyse LTI systems. From the convolution property Y (z)=H (z)X (z). Where: Y (z)= z-transform of system output.

If x(t) = Cos(3t + pi/4), it's periodic simply because it's a sinusoid.
