PROBLEM SPR-04-F.1: Circle the correct answer to each of the following short answer questions, and provide a short justification for your answer. 1. Pick the correct frequency response for the FIR filter: y [ n ] = x [ n ] + x [ n - 3]. (a) 2 cos ( 1 . 5 ˆ ω) (b) 2 e - j 1 . 5 ˆ ω cos ( 1 . 5 ˆ ω) (c) 2 e - j 1 . 5 ˆ ω cos ( 0 . 5 ˆ ω) (d) 2 e - j 2 ˆ ω cos ( ˆ ω) (e) none of the above 2. A sinusoidal signal x ( t ) is defined by: x ( t ) = e { ( 2 - j 2 ) e j π t } . When x ( t ) is plotted versus time ( t ) , its maximum value will be: (a) A = 1 (b) A = 2 - j 2 (c) A = 2 (d) A = 2 (e) none of the above 3. Determine the amplitude ( A ) and phase (φ) of the sinusoid that is the sum of the following three sinusoids: 10 cos ( 6 t + π/ 2 ) + 7 cos ( 6 t - π/ 6 ) + 7 cos ( 6 t + 5 π/ 6 ) , (a) A = 10 and φ = π/ 2.

### What students are saying

• 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.
