... transform of the imaginary odd function is real and odd.Let and refer to real and imaginary, and to even and odd, and lower-case and upper-case letters to time and frequency functions. A summary of the ... real and imaginary parts are plotted on the - and -axes, and time runs down the axis of thescrew. The complex conjugate of this signal reverses the -axis and gives the screw anopposite handedness. ... spectrum of a plane wave[ ], where the plane wave has a randomly fluctuating amplitude: say, randis a random number between , and the randomly modulated plane wave is [].5 Explain the horizontal...
