a) b) Consider the following C++ function where all variables are single bits: boolean FunctionZ (boolean a, boolean b, boolean c) { boolean x = a & b | c; boolean y = ~(x^ a); return y; } Draw the logic design that is a direct representation of this function (without simplifying). Bad drawings will lose points! Use algebraic simplification to simplify this function and write it as a "sum-of- products" format. Start off with this expression (as taken from the program function): y = (xa)
