DATA COMMUNICATION & NETWROKING COMP 310 ASSIGNMENT #2 ST.GEORGE’S UNIVERSITY LEOPOLDO PIRELA DUE DATE: SEPTEMBER 21ST‚ 2013 What is the phase shift for the following? a. A sine wave with the maximum amplitude at time zero b. A sine wave with maximum amplitude after 1/4 cycle c. A sine wave with zero amplitude after 3/4 cycle and increasing Solution: a. There is no phase shift at time zero b. (¼) 360 = 90 90 x 2π / 360 = 1.57 rad c. (¾) 360 = 270 270 x 2π / 360 = 4. 7 rad
