Hint: This is similar to the equal payment mortgage example. 5. Execute a the convolution of the following two sequences using: a. Direct solution of the convolution summation b. Using the tabular method c. Using the graphical method. 1 2 [ ] [1,0, 4,2,5, 2], [ ] [2, 2,1, 1,0,0] f k f k =--=--6. Find the convolution of the following functions. Use any one method you prefer. a. [ ] [ ] [ ] y k q k k δ = b. [ ] sin[ ] [ ] 2 y k k k π = c. [ ] [ ] [ 5] y k q k k =-d. [ ] [ ] [ ] y k q k q k = e. 3 [ ] [ 2] [ ] y k q k p k = + f. 3 3 [ ] [ ] [ ] y k p k p k = g. 2 4 [ ] [ ] [ ] y k p k p k = h. [ ] [ ] [ ] y k r k r k =...
