2 ii) Design a 10 th order Hamming windowed FIR low-pass filter with cut- off frequency at 1000 Hz if the sampling frequency is 8000 Hz. Hence, find an expression for the multipliers a ( k ), k = 0, 1, 2,…10 of the designed filter. 8 iii) How would you use these values to design a high-pass filter with cut- off at 1000 Hz. Explain your answer. 3 Total 25 1; ( ) 0; c j LP c H e ) ( ) sin( ] [ c c c LP n n n h

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.
