Finding the Energy of Average Power of the signal x(t)

WebA complex exponential signal is a decaying exponential signal when. Is the following signal an energy signal? x (t) = u (t) – u (t – 1) A continuous signal can be represented as the product of an impulse function and the signal itself. Determine the nature of the signal: x (t) = e-0.2t [cosΩt + jsinΩt]. Determine the power of the signal ... http://www.cse.lehigh.edu/~jingli/teach/F2005CT/hw/midterm1_sample_soln.pdf optimum machinery catalogue

Web$$\overline{x^2(t)}=\frac{1}{2T}\int_{-T}^T x(t) ^2dt$$ Note that \$\cos^2 x=\frac12 (1+\cos(2x))\$ and \$\sin^2 x=\frac12 (1-\cos(2x))\$. So after integrating over one period, the terms with double frequency and also the cross-term cancel out. So you finally get for the power $$\overline{x^2(t)}=10^2\cdot \frac12 + 5^2\cdot\frac12=62.5$$ Web(c) Find (directly) the exponential Fourier series for (𝑡). (d) Compare the signal’s exact power to that obtained using the dc and first 5 harmonic terms. (e) Plot the signal’s spectra. (f) Verify your work employing the provided Mathcad exponential Fourier series worksheet. Your turn: Consider the signal (𝑡), (𝑡)= sin(𝜋𝑡) WebConsider the following three continuous-time signals with a fundamental period of T= 1=2: x(t) = cos(4ˇt); y(t) = sin(4ˇt); z(t) = x(t)y(t): (a)Determine the Fourier series coe cients of … optimum long island tv schedule
