Subsampling in 1D: Consider fR-R. Say that you know the value f at N points ((ri,f( You wish to downsample this set of points by a factor of K, keeping every Kth sample starting with i C (where C -1) (a) (5 points) What are the indices of the set of points that are kept after subsampling? (b) (5 points) Let MM be the number of points that are kept after subsampling. Write a formula for Min terms of N,C and K. Hint: You may find it useful to use the floor J or ceiling .1 functions. (c) (5 points) Let fArr be an array storing f(Write pseudo-code for a function that takes fArr, N, C and K as inputs and outputs fSubArr that's the subsampled result
