Determine if the following signals are periodic. If yes, calculate the fundamental period for the signals. i) ) 2 8 / 5 sin( ) ( π + π = t t x ii) ( ) ( ) 5 3 cos 2 7 6 sin ) ( t t t x + π = iii) ( ) ( ) 6 8 exp 8 3 exp ) ( t t j t x π + π = 3. Show that the average power of the DT periodic signal x [ k ] = A cos( Ω k ) is given by A 2 /2. 4. Determine if the following signals are even, odd, or neither-even-nor-odd. In the later case, evaluate and sketch the even and odd components of the CT signals. i) ( ) ( ) ( ) [ ] t t t x π + π = 4 cos 2 2 sin 2 ii) ( ) ( ) t t t x 3 cos 2 + = iii) ࠵? t = 3࠵? 0 ≤ ࠵? ≤ 2 6 2 ≤ ࠵? ≤ 4 3(−࠵? + 6) 4 ≤ ࠵? ≤ 6 0 elsewhere 5.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
