Due Monday, 10/31/05 at 5 PM ECE 638 Homework No. 3 Fall 2005 1. a. Consider the signal f ( x , y ) shown below which has value 1 in the shaded areas, and value 0 , elsewhere. The bars are infinitely long along the y axis; and there are infinitely many of them along the x axis. Find a simple expression for the CSFT F ( u , v ) of this signal, and sketch it. b. Consider the signal g ( x , y ) shown below

- 2 - ECE 638 Homework No. 3 which has value 1 in the shaded areas, and value 0 , elsewhere. Here bars have length 24 along the y axis; but there are still infinitely many of them along the x axis. Find a simple expression for the CSFT G ( u , v ) of this signal, and sketch it. 2. For the function given below, do the following: i. Express f ( x , y ) in terms of the special functions given in class. ii. Find its CSFT F ( u , v ) using transform pairs and properties. iii. Sketch F ( u , v ) in enough detail to show that you know what it looks like. 3.
