need to find time-domain signal given its FS magnitude and phase graphs . . .
http://www.imageupload.org/thumb/thumb_55625.jpg (http://www.imageupload.org/?d=8923A1641)
from the graph we can conclude that X(k) will contain both real and imaginary parts
so x(t) can neither be odd nor be even . . .
but they've mentioned option A is correct answer which is even signal. . .
how is this possible ? . . .
