Chapter 8, Problem 8.9Q

10-3) similar to Lathi & Ding, Prob. P.6.3-7 The Fourier transform P(f) of a the basic pulse p(t) used in a certain binary communication is shown in the figure below: P(f) 1 0.5 0 f₁ = 0.8 √₂ = 1.2 f, MHz (a) From the shape of P(f), explain at what pulse rate this pulse would satisfy Nyquist's first criterion. (b) Assuming that the pulse is a raised-cosine pulse, find its rolloff factor. (c) Find p(t) and verify that this pulse satisfies Nyquist's first criterion in the time domain. (d) Show how rapidly the pulse decays as a function of t, (i.e., what power of t does the envelope obey for large time values).
