Write a matlab m-file that can be used to obtain the normalized elliptic transfer function for any given set of specifications {k, a_p, a_a} where k is the selectivity, a_p is maximum passband loss, and a_a is the minimum stopband loss. your program should also compute the actual stopband loss. use your program to obtain elliptic transfer functions for two different sets of specifications that would result in an even-order and an odd-order transfer function of order greater than 5. plot the loss characteristics associated with the transfer functions obtained.
