Determine the power of the signal x t cos t
WebJan 13, 2024 · A signal x(t) is said to be a power signal if and only if its average power is finite, thus implying that energy is infinite. ... Consider the signal x(t) = 10 cos (10πt + π/7) + 4 sin (30πt + π/8). Its power lying within the frequency band 10 Hz to 20 Hz is ... Webtcos(t) is odd, since t is odd and cos(t) is even. t2 sin(t) is odd, since t2 is even and sin(t) is odd. t3 sin(t)cos(t) is even, since t3 is odd, sin(t) is odd, and cos(t) is even. Therefore, by inspection, we may conclude that the even and odd com-ponents of x(t) are, respectively, xe(t) = 1+t3 sin(t)cos(t); and xo(t) = tcos(t)+t2 sin(t): Problem 1.3 Figure 1.15 shows a …
