Name BME 171, Fall 2000 - TEST #2 1. Compute Fourier transforms of the signals given below. Indicate which pairs and properties you are using. (a) x 1 ( t ) = e - 2( t - 1) u ( t - 1) (b) x 2 ( t ) = cos(6 πt ) t 2 +1 2. Consider the following signal: x ( t ) = 2 . 5 - 3 cos(2 π ( t - 0 . 25)) (a) Write x ( t ) in the complex exponential form. (b) Sketch amplitude and phase spectra of this signal (it helps to make a little table first). Label all pertinent features. 3. What are the two ways of computing average power of a periodic power signal?
