Unformatted text preview: (b) Are these signals periodic? If so, determine the period. (c) Are these nite energy or nite power signals? If nite power, determine P , and if nite energy, determine E and P . Determine these values both analytically and numerically. For numerical integration, use the approximation Z f ( t )d t X k f ( k t ) t, and try at least two dierent values of t . 3. [10] Oppenheim and Wilsky (O&W), problem 1.21. 4. [10] O&W, 1.22. 5. [15] O&W, 1.27. 6. [15] O&W, 1.34. 7. [15] Using the approximation ( t ) = 1 rect ( t ) as 0, show that (2 t ) = 1 2 ( t ) and u ( t ) = Z t ( ) d . 8. [15] O&W, 1.44(a). 1...
