Linear algebra (0 points) a (dual norm of L1 norm) The L1 norm k · k1 of a vector v 2 Rn is defined as kvk1 = nX i =1 jvij: (1) The dual norm k · k∗ of a norm k · k is defined as kvk∗ = sup kwk≤1 (v · w): (2) Compute the dual norm of the L1 norm. (Here v · w denotes the inner product between v and w: v · w , Pn i=1 viwi) Solution: We will prove that sup kwk1≤1 (v · w) = max i2[n] vi = kvk1 (3) which implies that the dua...

Exam (elaborations) TEST BANK FOR Fundamentals of Digital Communication By Upamanyu Madhow (Solution Manual) Solutions to Chapter 2 Problems Fundamentals of Digital Communication Problem 2.1: Rather than doing the details of the convolution, we simply sketch the shapes of the waveforms. For a signal s = sc + jss and a filter h = hc + jhs, the convolution y = s ∗ h = (sc ∗ hc − ss ∗ hs) + j(sc ∗ hs + ss ∗ hc) For h(t) = smf (t) = s(−t), rough sketches of Re(y), Im(y) and |y|...

Problem 2.1: Rather than doing the details of the convolution, we simply sketch the shapes of the waveforms. For a signal s = sc + jss and a filter h = hc + jhs, the convolution y = s ∗ h = (sc ∗ hc − ss ∗ hs) + j(sc ∗ hs + ss ∗ hc) For h(t) = smf (t) = s(−t), rough sketches of Re(y), Im(y) and |y| are shown in Figure 1. Clearly, the maximum occurs at t = 0. = c*hc −ss*hs Re(s* h) sc*hs ss*hc Im(s* h) |s* h| + = + s Figure 1: The convolution of a signal with its mat...

Complex numbers appeared in the textbook before in different topics. Solving linear homogeneous ODEs led to characteristic equations, (3), p. 54 in Sec. 2.2, with complex numbers in Example 5, p. 57, and Case III of the table on p. 58. Solving algebraic eigenvalue problems in Chap. 8 led to characteristic equations of matrices whose roots, the eigenvalues, could also be complex as shown in Example 4, p. 328. Whereas, in these type of problems, complex numbers appear almost naturally as compl...
