Problems 6-42 through 6-47 deal with the same two arrays, a and b, which we will assume have been defined in an HDL source file and have the following values: [a] = [10010111], [b] = [00101100]. Output array [z] is also an eight-bit array. Answer Problems 6-42 through 6-47 based on this information. (Assume undefined bits in z are 0.)

Give the value of z for each expression (identical AHDL and VHDL expressions are given):

(a)* z[] = a[] & b[]; (b)* z[] = a[] # b[]; (c) z[] = a[] $ !b[]; z
