Description

The Question

question in file about fourier transform f^(v)  of a function f of time.

(a) (3 points) The Fourier transform f?(? ) of a function f of time is shown in Figure

2. Suppose that the function f is sampled once per second. Sketch the Fourier

transform of the sampled function on the graph. Figure 2: Fourier transform for question 9

(b) (2 points) What should the sample rate be so that the original function can be

recovered from the samples with no error? Assume the units for frequency are

Hertz. Briefly justify your answer. f(t) = t on [??, ?] = 2[(-1)n+1/n sint

2[(-1)n+1/n sinpi - 2[(-1)n+1/n sin(-pi) = 2[(-1)n+1/n(sinpi -sin(-pi)) = 0.22*(-1)n+1/n

but, i = (-1)1/2

Thus, 0.22*(-1)n+1/n =0.22i2(n+1)/n
