11.03.1 Multiple Choice-Test Chapter 11.03 Fourier Transform Pair: Frequency and Time Domain 1. Given two complex numbers: i C i C 4 1 and , 3 2 2 1 + = = . The product 2 1 C C P × = can be computed as (A) i 5 2 + (B) i 5 10 + (C) i 5 14 + (D) i 5 14 + 2. Given the complex number i C 4 3 1 + = . In polar coordinates, the above complex number can be expressed as θ i Ae C = 1 , where A and is called the amplitude and phase angle of 1 C , respectively. The amplitude A can be computed as (A) 3 (B) 4 (C) 5 (D) 7 3. Given the complex number i C 4 3 1 + = . In polar coordinates, the above complex number can be expressed as i Ae C = 1 , where A and is called the amplitude and phase angle of 1 C , respectively. The phase angle in radians can be computed as (A) 0.6435 (B) 0.9273 (C) 2.864 (D) 5.454 4. For the complex number , 4
