Experiments: 1.1 Time-Domain The filterfir.mat file contains the provided code for the function filterfir. Generally, this functions performed the summation function know as convolution. It takes in the two vectors h and x and starts by using the length function to obtain each vector s length then uses that data to calculate the length of the output vector. Then, the filterfir creates a vector of zeros which the output will be stored to. In MATLAB, performing summations is easy because of the use of loops. Filterfir takes advange of that to perform the weighted summation equation which is equivalent to the convolution of the two vectors. Finally, the function returns the output to the user. I then made two vectors according to the specifications in the lab manual. I used the code y=filterfir(x,avg10); to run the two vectors through my function. The variable y is assigned the output which is the convolution of the vectors x and avg10.

    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.
