Design a logic circuit to produce a HIGH output only if the input, represented by a 4-bit binary number(A(MSB) ,B ,C and D(LSB)), is greater than eleven or less than five(not including eleven and five). Find the logic expression Y is(______).设计一个组合逻辑电路满足要求:当输入代表的4位二进制数(A(位权最高)、B 、C 和 D(位权最低))取值大于11或小于5(不包含11 和 5)时输出为高电平。则其逻辑表达式为(______)。
