8. A water purification plant uses one tank for chemical sterilization and a second, larger tank for settling and aeration. Each tank is equipped with two sensors that measure the height of water in each tank and the flow rate of water into each tank. When the height or the flow rate of water is too high, the sensors produce a logic high output. Design a logic circuit that sounds an alarm whenever the height of water in both tanks is too high and either of the flow rates is too high, or whenever both flow rates are too high and the height of water in either tank is too high AfAf AhAh BfBf BhBh O 00000 00010 00100 00110 01000 01010 01100 01111 10000 10010 10100 10111 11000 11011 11101 11111 00011110 000000 010010 110111 100010 AfAhAfAh BfBhBfBh A f A h B h + A f A h B f + B f B h A f + B f B h A h A f A h (B f +B h ) + B f B h (A f +A h )
