B) Consider the system in Figure 1.1. x(t) is sampled with a periodic impulse train, and a reconstructed signal x, (t) is obtained from the samples by lowpass filtering. The sampling period T = 1 ms, and x (t) is a sinusoidal signal of the form x(t) = cos (2π fot + 0). x(t) xp (1) p(t) = 8(t-nT) H(M) Figure 1.1 For each of the following choices of fo and 0, determine x, (t). 1) fo=250 Hz, 0 = π/4 2) fo = 750 Hz, 0 = π/2 x,(1)
